-=item B<setlogsock($sock_type, $stream_location)> (added in 5.004_02)
+Sys::Syslog - Perl interface to the UNIX syslog(3) calls
-Sets the socket type to be used for the next call to
-C<openlog()> or C<syslog()> and returns true on success,
-C<undef> on failure.
+=head1 VERSION
-A value of C<"unix"> will connect to the UNIX domain socket (in some
-systems a character special device) returned by the C<_PATH_LOG> macro
-(if your system defines it), or F</dev/log> or F</dev/conslog>,
-whatever is writable. A value of 'stream' will connect to the stream
-indicated by the pathname provided as the optional second parameter.
-(For example Solaris and IRIX require C<"stream"> instead of C<"unix">.)
-A value of C<"inet"> will connect to an INET socket (either C<tcp> or C<udp>,
-tried in that order) returned by C<getservbyname()>. C<"tcp"> and C<"udp">
-can also be given as values. The value C<"console"> will send messages
-directly to the console, as for the C<"cons"> option in the logopts in
-C<openlog()>.
+Version 0.15
-A reference to an array can also be passed as the first parameter.
-When this calling method is used, the array should contain a list of
-sock_types which are attempted in order.

+Call C<syslog()> with a string priority and a list of C<printf()> args
+just like C<syslog(3)>.

+C<Sys::Syslog> exports the following C<Exporter> tags:
- openlog($program, 'cons,pid', 'user');
- syslog('info', '%s', 'this is another test');
- syslog('mail|warning', 'this is a better test: %d', time);
- closelog();
+=over 4
+
+=item *
+
+C<:standard> exports the standard C<syslog(3)> functions:
+
+ openlog closelog setlogmask syslog
+
+=item *
+
+C<:extended> exports the Perl specific functions for C<syslog(3)>:
+
+ setlogsock
+
+=item *
+
+C<:macros> exports the symbols corresponding to most of your C<syslog(3)>
+macros and the C<LOG_UPTO()> and C<LOG_MASK()> functions.
+See L<"CONSTANTS"> for the supported constants and their meaning.
+
+=back
+
+By default, C<Sys::Syslog> exports the symbols from the C<:standard> tag.
+
+
+=head1 FUNCTIONS
+
+=over 4
+
+=item B<openlog($ident, $logopt, $facility)>
+
+Opens the syslog.
+C<$ident> is prepended to every message. C<$logopt> contains zero or
+more of the options detailed below. C<$facility> specifies the part
+of the system to report about, for example C<LOG_USER> or C<LOG_LOCAL0>:
+see L<"Facilities"> for a list of well-known facilities, and your
+C<syslog(3)> documentation for the facilities available in your system.
+Check L<"SEE ALSO"> for useful links. Facility can be given as a string
+or a numeric macro.
+
+This function will croak if it can't connect to the syslog daemon.
+
+Note that C<openlog()> now takes three arguments, just like C<openlog(3)>.
+
+B<You should use C<openlog()> before calling C<syslog()>.>
+
+B<Options>
+
+=over 4
+
+=item *
+
+C<cons> - This option is ignored, since the failover mechanism will drop
+down to the console automatically if all other media fail.
+
+=item *
+
+C<ndelay> - Open the connection immediately (normally, the connection is
+opened when the first message is logged).
+
+=item *
+
+C<nofatal> - When set to true, C<openlog()> and C<syslog()> will only
+emit warnings instead of dying if the connection to the syslog can't
+be established.
+
+=item *
+
+C<nowait> - Don't wait for child processes that may have been created
+while logging the message. (The GNU C library does not create a child
+process, so this option has no effect on Linux.)
+
+=item *
+
+C<pid> - Include PID with each message.
+
+=back
+
+B<Examples>
+
+Open the syslog with options C<ndelay> and C<pid>, and with facility C<LOCAL0>:
+
+ openlog($name, "ndelay,pid", "local0");
+
+Same thing, but this time using the macro corresponding to C<LOCAL0>:
+
+ openlog($name, "ndelay,pid", LOG_LOCAL0);
+
+
+=item B<syslog($priority, $message)>
+
+=item B<syslog($priority, $format, @args)>
+
+If C<$priority> permits, logs C<$message> or C<sprintf($format, @args)>
+with the addition that C<%m> in $message or C<$format> is replaced with
+C<"$!"> (the latest error message).
+
+C<$priority> can specify a level, or a level and a facility. Levels and
+facilities can be given as strings or as macros.
+
+If you didn't use C<openlog()> before using C<syslog()>, C<syslog()> will
+try to guess the C<$ident> by extracting the shortest prefix of
+C<$format> that ends in a C<":">.
+
+B<Examples>
+
+ syslog("info", $message); # informational level
+ syslog(LOG_INFO, $message); # informational level
+
+ syslog("info|local0", $message); # information level, Local0 facility
+ syslog(LOG_INFO|LOG_LOCAL0, $message); # information level, Local0 facility
+
+=over 4
+
+=item B<Note>
+
+C<Sys::Syslog> version v0.07 and older passed the C<$message> as the
+formatting string to C<sprintf()> even when no formatting arguments
+were provided. If the code calling C<syslog()> might execute with
+older versions of this module, make sure to call the function as
+C<syslog($priority, "%s", $message)> instead of C<syslog($priority,
+$message)>. This protects against hostile formatting sequences that
+might show up if $message contains tainted data.
+
+=back
+
+
+=item B<setlogmask($mask_priority)>
+
+Sets the log mask for the current process to C<$mask_priority> and
+returns the old mask. If the mask argument is 0, the current log mask
+is not modified. See L<"Levels"> for the list of available levels.
+You can use the C<LOG_UPTO()> function to allow all levels up to a
+given priority (but it only accept the numeric macros as arguments).
+
+B<Examples>
+
+Only log errors:
+
+ setlogmask( LOG_MASK(LOG_ERR) );
+
+Log everything except informational messages:
+
+ setlogmask( ~(LOG_MASK(LOG_INFO)) );
+
+Log critical messages, errors and warnings:
+
+ setlogmask( LOG_MASK(LOG_CRIT) | LOG_MASK(LOG_ERR) | LOG_MASK(LOG_WARNING) );
+
+Log all messages up to debug:
+
+ setlogmask( LOG_UPTO(LOG_DEBUG) );
+
+
+=item B<setlogsock($sock_type)>
+
+=item B<setlogsock($sock_type, $stream_location)> (added in 5.004_02)
+
+Sets the socket type to be used for the next call to
+C<openlog()> or C<syslog()> and returns true on success,
+C<undef> on failure.
+
+A value of C<"unix"> will connect to the UNIX domain socket (in some
+systems a character special device) returned by the C<_PATH_LOG> macro
+(if your system defines it), or F</dev/log> or F</dev/conslog>,
+whatever is writable. A value of 'stream' will connect to the stream
+indicated by the pathname provided as the optional second parameter.
+(For example Solaris and IRIX require C<"stream"> instead of C<"unix">.)
+A value of C<"inet"> will connect to an INET socket (either C<tcp> or C<udp>,
+tried in that order) returned by C<getservbyname()>. C<"tcp"> and C<"udp">
+can also be given as values. The value C<"console"> will send messages
+directly to the console, as for the C<"cons"> option in the logopts in
+C<openlog()>.
+
+A reference to an array can also be passed as the first parameter.
+When this calling method is used, the array should contain a list of
+sock_types which are attempted in order.
+
+The default is to try C<tcp>, C<udp>, C<unix>, C<stream>, C<console>.
+
+Giving an invalid value for C<$sock_type> will croak.
+
+
+=item B<closelog()>
+
+Closes the log file and return true on success.
+
+=back
+
+
+=head1 EXAMPLES
+
+ openlog($program, 'cons,pid', 'user');
+ syslog('info', '%s', 'this is another test');
+ syslog('mail|warning', 'this is a better test: %d', time);
+ closelog();
syslog('debug', 'this is the last test');

+=head1 NAME
+
+ppport.h - Perl/Pollution/Portability version 3.06
+
+=head1 SYNOPSIS
+
+ perl ppport.h [options] [files]
+
+ --help show short help
+
+ --patch=file write one patch file with changes
+ --copy=suffix write changed copies with suffix
+ --diff=program use diff program and options
+
+ --compat-version=version provide compatibility with Perl version
+ --cplusplus accept C++ comments
+
+ --quiet don't output anything except fatal errors
+ --nodiag don't show diagnostics
+ --nohints don't show hints
+ --nochanges don't suggest changes
+
+ --list-provided list provided API
+ --list-unsupported list unsupported API
+ --api-info=name show Perl API portability information
+
+=head1 COMPATIBILITY
+
+This version of F<ppport.h> is designed to support operation with Perl
+installations back to 5.003, and has been tested up to 5.9.2.
+
+=head1 OPTIONS
+
+=head2 --help
+
+Display a brief usage summary.
+
+=head2 --patch=I<file>
+
+If this option is given, a single patch file will be created if
+any changes are suggested. This requires a working diff program
+to be installed on your system.
+
+=head2 --copy=I<suffix>
+
+If this option is given, a copy of each file will be saved with
+the given suffix that contains the suggested changes. This does
+not require any external programs.
+
+If neither C<--patch> or C<--copy> are given, the default is to
+simply print the diffs for each file. This requires either
+C<Text::Diff> or a C<diff> program to be installed.
+
+=head2 --diff=I<program>
+
+Manually set the diff program and options to use. The default
+is to use C<Text::Diff>, when installed, and output unified

+=head2 --compat-version=I<version>
+
+Tell F<ppport.h> to check for compatibility with the given
+Perl version. The default is to check for compatibility with Perl
+version 5.003. You can use this option to reduce the output
+of F<ppport.h> if you intend to be backward compatible only
+up to a certain Perl version.
+
+=head2 --cplusplus
+
+Usually, F<ppport.h> will detect C++ style comments and

+=head2 --nodiag
+
+Don't output any diagnostic messages. Only portability

+=head2 --nohints
+
+Don't output any hints. Hints often contain useful portability

+
+=head2 --nochanges
+
+Don't suggest any changes. Only give diagnostic output and hints

+
+=head2 --list-provided
+
+Lists the API elements for which compatibility is provided by

+
+=head1 DESCRIPTION
+
+In order for a Perl extension (XS) module to be as portable as possible
+across differing versions of Perl itself, certain steps need to be taken.
+
+=over 4
+
+=item *
+
+Including this header is the first major one. This alone will give you
+access to a large part of the Perl API that hasn't been available in
+earlier Perl releases. Use
+
+ perl ppport.h --list-provided
+
+to see which API elements are provided by ppport.h.
+
+=item *
+
+You should avoid using deprecated parts of the API. For example, using
+global Perl variables without the C<PL_> prefix is deprecated. Also,
+some API functions used to have a C<perl_> prefix. Using this form is
+also deprecated. You can safely use the supported API, as F<ppport.h>
+will provide wrappers for older Perl versions.
+
+=item *
+
+If you use one of a few functions that were not present in earlier
+versions of Perl, and that can't be provided using a macro, you have
+to explicitly request support for these functions by adding one or
+more C<#define>s in your source code before the inclusion of F<ppport.h>.
+
+These functions will be marked C<explicit> in the list shown by
+C<--list-provided>.
+
+Depending on whether you module has a single or multiple files that
+use such functions, you want either C<static> or global variants.
+
+For a C<static> function, use:
+
+ #define NEED_function
+
+For a global function, use:
+
+ #define NEED_function_GLOBAL
+
+Note that you mustn't have more than one global request for one
+function in your project.
+
+ Function Static Request Global Request
+ -----------------------------------------------------------------------------------------
+ eval_pv() NEED_eval_pv NEED_eval_pv_GLOBAL
+ grok_bin() NEED_grok_bin NEED_grok_bin_GLOBAL
+ grok_hex() NEED_grok_hex NEED_grok_hex_GLOBAL
+ grok_number() NEED_grok_number NEED_grok_number_GLOBAL
+ grok_numeric_radix() NEED_grok_numeric_radix NEED_grok_numeric_radix_GLOBAL
+ grok_oct() NEED_grok_oct NEED_grok_oct_GLOBAL
+ newCONSTSUB() NEED_newCONSTSUB NEED_newCONSTSUB_GLOBAL
+ newRV_noinc() NEED_newRV_noinc NEED_newRV_noinc_GLOBAL
+ sv_2pv_nolen() NEED_sv_2pv_nolen NEED_sv_2pv_nolen_GLOBAL
+ sv_2pvbyte() NEED_sv_2pvbyte NEED_sv_2pvbyte_GLOBAL
+ sv_catpvf_mg() NEED_sv_catpvf_mg NEED_sv_catpvf_mg_GLOBAL
+ sv_catpvf_mg_nocontext() NEED_sv_catpvf_mg_nocontext NEED_sv_catpvf_mg_nocontext_GLOBAL
+ sv_setpvf_mg() NEED_sv_setpvf_mg NEED_sv_setpvf_mg_GLOBAL
+ sv_setpvf_mg_nocontext() NEED_sv_setpvf_mg_nocontext NEED_sv_setpvf_mg_nocontext_GLOBAL
+ vnewSVpvf() NEED_vnewSVpvf NEED_vnewSVpvf_GLOBAL
+
+To avoid namespace conflicts, you can change the namespace of the
+explicitly exported functions using the C<DPPP_NAMESPACE> macro.
+Just C<#define> the macro before including C<ppport.h>:
+
+ #define DPPP_NAMESPACE MyOwnNamespace_
+ #include "ppport.h"
+
+The default namespace is C<DPPP_>.
+
+=back
+
+The good thing is that most of the above can be checked by running
+F<ppport.h> on your source code. See the next section for
+details.
+
+=head1 EXAMPLES
+
+To verify whether F<ppport.h> is needed for your module, whether you
+should make any changes to your code, and whether any special defines
+should be used, F<ppport.h> can be run as a Perl script to check your
+source code. Simply say:
+
+ perl ppport.h
+
+The result will usually be a list of patches suggesting changes
+that should at least be acceptable, if not necessarily the most
+efficient solution, or a fix for all possible problems.
+
+If you know that your XS module uses features only available in
+newer Perl releases, if you're aware that it uses C++ comments,
+and if you want all suggestions as a single patch file, you could
+use something like this:
+
+ perl ppport.h --compat-version=5.6.0 --cplusplus --patch=test.diff
+
+If you only want your code to be scanned without any suggestions
+for changes, use:
+
+ perl ppport.h --nochanges
+
+You can specify a different C<diff> program or options, using
+the C<--diff> option:
+
+ perl ppport.h --diff='diff -C 10'
+
+This would output context diffs with 10 lines of context.
+
+To display portability information for the C<newSVpvn> function,
+use:
+
+ perl ppport.h --api-info=newSVpvn
+
+Since the argument to C<--api-info> can be a regular expression,
+you can use
+
+ perl ppport.h --api-info=/_nomg$/
+
+to display portability information for all C<_nomg> functions or
+
+ perl ppport.h --api-info=/./
+
+to display information for all known API elements.
+
+=head1 BUGS
+
+If this version of F<ppport.h> is causing failure during
+the compilation of this module, please check if newer versions
+of either this module or C<Devel::PPPort> are available on CPAN
+before sending a bug report.
+
+If F<ppport.h> was generated using the latest version of
+C<Devel::PPPort> and is causing failure of this module, please
+file a bug report using the CPAN Request Tracker at L<http://rt.cpan.org/>.
+
+Please include the following information:
