=head1 NAME
FCGI - Fast CGI module
use FCGI;
- $count = 0;
- while(FCGI::accept() >= 0) {
- print("Content-type: text/html\r\n\r\n", ++$count);
+ my $count = 0;

+
+ while($request->Accept() >= 0) {
+ print("Content-type: text/html\r\n\r\n", ++$count);
}
=head1 DESCRIPTION
=over 4
-=item FCGI::accept()
+=item FCGI::Request
+
+Creates a request handle. It has the following optional parameters:
+
+=over 8
+
+=item input perl file handle (default: \*STDIN)
+
+=item output perl file handle (default: \*STDOUT)
+
+=item error perl file handle (default: \*STDERR)
+
+These filehandles will be setup to act as input/output/error
+on successful Accept.
+
+=item environment hash reference (default: \%ENV)
+
+The hash will be populated with the environment.
-Accepts a connection. Returns 0 on success.
+=item socket (default: 0)
+
+Socket to communicate with the server.
+Can be the result of the OpenSocket function.
+For the moment, it's the file descriptor of the socket
+that should be passed. This may change in the future.
+
+You should only use your own socket if your program
+is not started by a process manager such as mod_fastcgi
+(except for the FastCgiExternalServer case) or cgi-fcgi.
+If you use the option, you have to let your FastCGI
+server know which port (and possibly server) your program
+is listening on.
+See remote.pl for an example.
+
+=item flags (default: FCGI::FAIL_ACCEPT_ON_INTR)
+
+Possible values:
+
+=over 12
+
+=item FCGI::FAIL_ACCEPT_ON_INTR
+
+If set, Accept will fail if interrupted.
+It not set, it will just keep on waiting.
+

+
+Example usage:
+ my $req = FCGI::Request;
+
+or:
+ my %env;
+ my $in = new IO::Handle;
+ my $out = new IO::Handle;
+ my $err = new IO::Handle;
+ my $req = FCGI::Request($in, $out, $err, \%env);
+
+=item FCGI::OpenSocket(path, backlog)
+
+Creates a socket suitable to use as an argument to Request.
+
+=over 8
+
+=item path
+
+Pathname of socket or colon followed by local tcp port.
+Note that some systems take file permissions into account
+on Unix domain sockets, so you'll have to make sure that
+the server can write to the created file, by changing
+the umask before the call and/or changing permissions and/or
+group of the file afterwards.
+
+=item backlog
+
+Maximum length of the queue of pending connections.
+If a connection
+request arrives with the queue full the client may receive
+an error with an indication of ECONNREFUSED.
+
+=back
+
+=item FCGI::CloseSocket(socket)
+
+Close a socket opened with OpenSocket.
+
+=item $req->Accept()
+
+Accepts a connection on $req, attaching the filehandles and
+populating the environment hash.
+Returns 0 on success.
If a connection has been accepted before, the old
one will be finished first.
-=item FCGI::finish()
+Note that unlike with the old interface, no die and warn
+handlers are installed by default. This means that if
+you are not running an sfio enabled perl, any warn or
+die message will not end up in the server's log by default.
+It is advised you set up die and warn handlers yourself.
+FCGI.pm contains an example of die and warn handlers.
+
+=item $req->Finish()
Finishes accepted connection.
+Also detaches filehandles.
-=item FCGI::flush()
+=item $req->Flush()
Flushes accepted connection.
-=item FCGI::set_exit_status(status)
+=item $req->Detach()
-Sets the exit status that finish returns to the server.
+Temporarily detaches filehandles on an accepted connection.
-=item FCGI::start_filter_data()
+=item $req->Attach()
-Does anyone use this function ?
+Re-attaches filehandles on an accepted connection.
+
+=item $req->LastCall()
+
+Tells the library not to accept any more requests on this handle.
+It should be safe to call this method from signal handlers.
+
+Note that this method is still experimental and everything
+about it, including its name, is subject to change.
+
+=item $env = $req->GetEnvironment()
+
+Returns the environment parameter passed to FCGI::Request.
+
+=item ($in, $out, $err) = $req->GetHandles()
+
+Returns the file handle parameters passed to FCGI::Request.
+
+=item $isfcgi = $req->IsFastCGI()
+
+Returns whether or not the program was run as a FastCGI.

+=head1 LIMITATIONS
+
+FCGI.pm isn't Unicode aware, only characters within the range 0x00-0xFF are
+supported. Attempts to output strings containing characters above 0xFF results
+in a exception: (F) C<Wide character in %s>.
+
+Users who wants the previous (FCGI.pm <= 0.68) incorrect behavior can disable the
+exception by using the C<bytes> pragma.
+
+ {
+ use bytes;
+ print "\x{263A}";
+ }
