Hi,
Where do I find the definitions (assuming such exist) that I can
use to
determine from within an XSub:
1) The operating system in use (specifically, whether it's Cygwin);
2) The version of perl (specifically, whether it's >= 5.6.1);
In the past I've used the values of $] and $^O to DEFINE my own
symbols in
the Makefile.PL - which works fine, but is a little silly if the
info the
XSub needs is already available.
You can use those variables in XS the same as in perl code.
Sorry - I didn't specify it, but I was wanting to do it with the
pre-processor:
I think you can check for Cygwin with
#ifdef __CYGWIN__
and you can check the perl version using the defines
PERL_REVISION
PERL_VERSION
PERL_SUBVERSION
from perl's patchlevel.h
