2988 * This symbol indicates how much support of the void type is given by this
2989 * compiler. What various bits mean:
2991 * 1 = supports declaration of void
2992 * 2 = supports arrays of pointers to functions returning void
2993 * 4 = supports comparisons between pointers to void functions and
2994 * addresses of void functions
2995 * 8 = suports declaration of generic void pointers
2997 * The package designer should define VOIDUSED to indicate the requirements
2998 * of the package. This can be done either by #defining VOIDUSED before
2999 * including config.h, or by defining defvoidused in Myinit.U. If the
3000 * latter approach is taken, only those flags will be tested. If the
3001 * level of void support necessary is not present, defines void to int.

3012 /* PERL_XS_APIVERSION:
3013 * This variable contains the version of the oldest perl binary
3014 * compatible with the present perl. perl.c:incpush() and

3016 * directories across major versions back to xs_apiversion.
3017 * This is only useful if you have a perl library directory tree

3019 * See INSTALL for how this works.

3021 * so that is the lowest possible value.
3022 * Since this can depend on compile time options (such as
3023 * bincompat) it is set by Configure. Other non-default sources
3024 * of potential incompatibility, such as multiplicity, threads,

3030 * This variable contains the version of the oldest perl

3032 * written for pm_apiversion will still work for the current
3033 * version). perl.c:incpush() and lib/lib.pm will automatically
3034 * search in $sitelib for older directories across major versions
3035 * back to pm_apiversion. This is only useful if you have a perl
3036 * library directory tree structured like the default one. The
3037 * versioned site_perl library was introduced in 5.005, so that's
3038 * the default setting for this variable. It's hard to imagine
3039 * it changing before Perl6. It is included here for symmetry
3040 * with xs_apiveprsion -- the searching algorithms will
3041 * (presumably) be similar.
