It takes one argument, a list of key-value pairs, in which the following
keys are recognized:
-=over
+=over 4
-=item NAME
+=item DLBASE
-This gives the name of the extension (I<e.g.> Tk::Canvas) for which
-the linker option file will be produced.
+This item specifies the name by which the linker knows the
+extension, which may be different from the name of the
+extension itself (for instance, some linkers add an '_' to the
+name of the extension). If it is not specified, it is derived
+from the NAME attribute. It is presently used only by OS2 and Win32.
=item DL_FUNCS
associative array, in which each key is the name of a package, and
each value is an a reference to an array of function names which
should be exported by the extension. For instance, one might say
-C<DL_FUNCS =E<gt> { Homer::Iliad =E<gt> [ qw(trojans greeks) ],
+C<DL_FUNCS =E<gt> { Homer::Iliad =E<gt> [ qw(trojans greeks) ],
Homer::Odyssey =E<gt> [ qw(travellers family suitors) ] }>. The
function names should be identical to those in the XSUB code;
C<Mksymlists> will alter the names written to the linker option
This key can be used to specify the name of the linker option file
(minus the OS-specific extension), if for some reason you do not
want to use the default value, which is the last word of the NAME
-attribute (I<e.g.> for Tk::Canvas, FILE defaults to 'Canvas').
+attribute (I<e.g.> for C<Tk::Canvas>, FILE defaults to C<Canvas>).
=item FUNCLIST
exported from the extension. Its value is a reference to an
array of function names to be exported by the extension. These
names are passed through unaltered to the linker options file.
+Specifying a value for the FUNCLIST attribute suppresses automatic
+generation of the bootstrap function for the package. To still create
+the bootstrap name you have to specify the package name in the
+DL_FUNCS hash:
-=item DLBASE
+ Mksymlists({ NAME => $name ,
+ FUNCLIST => [ $func1, $func2 ],
+ DL_FUNCS => { $pkg => [] } });
-This item specifies the name by which the linker knows the
-extension, which may be different from the name of the
-extension itself (for instance, some linkers add an '_' to the
-name of the extension). If it is not specified, it is derived
-from the NAME attribute. It is presently used only by OS2.
+
+=item IMPORTS
+
+This attribute is used to specify names to be imported into the
+extension. It is currently only used by OS/2 and Win32.
+
+=item NAME
+
+This gives the name of the extension (I<e.g.> C<Tk::Canvas>) for which
+the linker option file will be produced.
