Special variables in XS/C

[Beau E. Cox]

Hi -

Does anyone know where access to the perl special variables
($!, $@, $/, etc.) from c-code is documented? I can't seem
to find any mention in the perl pods (guts, call, api, etc.)?

Aloha => Beau;

These things are not as accessible as one would wish:

ERRNO in ?, ERRSV in perlcall and section "Warning and Dieing" in
perlapi, PL_rs in perlintern.

Thanks Randy -

For example, I am sucessfully using:

SV *ERRNO = get_sv( "!", TRUE );
printf( "error number is %d\n", SvIV( ERRNO ) );
printf( "error string is %s\n", SvPV_nolen( ERRNO ) );
...

All global special varibales are now at my fingertips!
