I know there is a way to call Perl routines from C. As shown here
http://search.cpan.org/dist/perl/pod/perlcall.pod#NAME
But, still I do not see a widespread use of this by C programmers. Has any one used this …ever? or any idea what are the reasons that it is not used so much?
Well, the most well known example of a C program embedding perl is Apache and mod_perl, which lets people access the Apache API through Perl.
You probably don’t see many programs embedding perl because they don’t need it as a feature. Why don’t more C programs send email? 🙂
