=head1 DESCRIPTION
=head1 USAGE
-Generally one only needs to call the 3 functions shown in the synopsis,
-C<constant_types()>, C<C_constant> and C<XS_constant>.
+Generally one only needs to call the C<WriteConstants> function, and then
+
+ #include "constants.c"
+
+in the C section of C<Foo.xs>
+
+ INCLUDE constants.xs
+
+in the XS section of C<Foo.xs>.
+
+For greater flexibility use C<constant_types()>, C<C_constant> and
+C<XS_constant>, with which C<WriteConstants> is implemented.
Currently this module understands the following types. h2xs may only know
a subset. The sizes of the numeric types are chosen by the C<Configure>
%EXPORT_TAGS = ( 'all' => [ qw(
XS_constant constant_types return_clause memEQ_clause C_stringify
- C_constant autoload
+ C_constant autoload WriteConstants
) ] );
@EXPORT_OK = ( @{ $EXPORT_TAGS{'all'} } );
An internal function. I<WHAT> should be a hashref of types the constant
function will return. I<params> returns the list of flags C<$use_iv, $use_nv,
-$use_pv> to show which combination of pointers will be needed in the C
-argument list.

+=item WriteConstants ATTRIBUTE =E<gt> VALUE [, ...]
+
+Writes a file of C code and a file of XS code which you should C<#include>
+and C<INCLUDE> in the C and XS sections respectively of your module's XS
+code. You probaby want to do this in your C<Makefile.PL>, so that you can
+easily edit the list of constants without touching the rest of your module.
+The attributes supported are
+
+=over 4
+
+=item NAME
+
+Name of the module. This must be specified
+
+=item DEFAULT_TYPE
+
+The default type for the constants. If not specified C<IV> is assumed.
+
+=item BREAKOUT_AT
+
+The names of the constants are grouped by length. Generate child subroutines
+for each group with this number or more names in.
+
+=item NAMES
+
+An array of constants' names, either scalars containing names, or hashrefs
+as detailed in L<"C_constant">.
+
+=item C_FILE
+
+The name of the file to write containing the C code. The default is
+C<constants.c>.
+
+=item XS_FILE
+
+The name of the file to write containing the XS code. The default is
+C<constants.xs>.
+
+=item SUBNAME
+
+The perl visible name of the XS subroutine generated which will return the
+constants. The default is C<constant>.
+
+=item C_SUBNAME
+
+The name of the C subroutine generated which will return the constants.
+The default is I<SUBNAME>. Child subroutines have C<_> and the name
+length appended, so constants with 10 character names would be in
+C<constant_10> with the default I<XS_SUBNAME>.
