Do any of you have a good C wrapper program that checks two agrument values syntax, to make sure they are just characters, and then these agruments are passed to a perl script. This Perl script sets the effective UID, "which is root" and then it untaints the agruments so that it can be run as suid.

The C wrapper and everything else works fine, but I want to be able to check the syntax of the two agruments in C, before they are passed to the perl script, and I'm not sure how to do that.

Here's my C wrapper

#include <stdio.h>
#include <string.h>
#include <unistd.h> /* for exec */

main(argc, argv)
        int             argc;
        char    *argv [];
{

/* Make sure at least one argument is passed to this program */
    if (argc < 2) {
        printf ("Usage: ldap-group [-p] trans \n");
        exit(1);
    }

/* execute the perl script */

execv("/opt/bin/techweb-changes.pl",argv);

}
/* END OF MAIN PROGRAM */
