A c program, no. A c library yes. <toot>Check out my tutorial</toot> (especially the section titled Exposing a Library). Here's the code snippet from that tutorial:

#!/usr/bin/perl

use Inline C => DATA =>
       LIBS => '-lservices';

# Here's how we would configure Inline if our headers and
# libraries are in a non-standard location 

#use Inline C => DATA =>
#           INC  => '-I/usr/local/include' =>
#           LIBS => '-L/usr/local/lib -lservices';

my_services();

__END__
__C__

#include <libservices.h>

int my_services( ) {
   struct serv *serv_list = serv_load(NULL);
   struct serv *serv = serv_list;

   for (; serv; serv = serv->next) {
      printf("%s %s %s \n", serv->name, serv->port, serv->proto );
   }
  serv_destroy(serv_list);
  return 1;
}
