in reply to Forks.pm dilemma

Maybe I'm missing something, but won't something like this work:

/* --- PerlVersionDemo.xs --- */ #include "EXTERN.h" #include "perl.h" #include "XSUB.h" #include <stdio.h> void print_hello_561 (void) { printf("hello world from perl 5.6.1\n"); } void print_hello_58 (void) { printf("hello world from perl 5.8 or higher\n"); } MODULE = PerlVersionDemo PACKAGE = PerlVersionDemo #if (PERL_REVISION == 5) && (PERL_VERSION == 6) && (PERL_SUBVERSION == + 1) void print_hello() CODE: print_hello_561(); #else # if (PERL_REVISION == 5) && (PERL_VERSION >=8) void print_hello() CODE: print_hello_58(); # endif #endif

Just stick your PROTOTYPE in the perl 5.8.x bit and it will be ignored on earlier perls.

Update: So, your share_561() would accept a regular variable and pass a reference to the actual share()

[LanX]: before digging into deep debugging ... I have a strange UTF8 problem, probably it rings a bell:
[LanX]: two utf8 strings from different sources are base64 encoded, but after joining both the umlauts in teh second get deleted
[Corion]: LanX: You can't just join two base64 strings together
[LanX]: (not a high priority bug because I can use some HTML entities in the second string)
[Corion]: base64 is padded to a multiple of 4 chars (or something)
[LanX]: misunderstanding, I joined them before converting to base64
[Corion]: Also, I would be wary of encodings and try to make really sure that both input strings are UTF-8. Maybe join the input strings from one source together to see whether they decode as bad or not
[Corion]: LanX: Then the problem should persist without encoding to base64 too ;)
