problem with example of mpn_gcd

[Blake Huff]

Wow that was a rude response.  Not ALL of us are natural born  
programmers, and most of us get in over our head at some point.   
Anyways, here's some examples of how to call the gmp functions from  
your code.  Anyways, as Decio pointed out, these are rather  
elementary C issues, so I suggest you brush up on your programming  
before jumping into the GMP functions.  There are certainly some  
lists for C learners.

#include <stdio.h>
#include <gmp.h>

main (int argc, char **argv){

       mpz_t a, b, p;

       if (argc != 3)
         { printf ("Usage: %s <number> <number>\n", argv[0]); return  
(1); }

       /* Initialize and assign a and b from base 10 strings in argv */
       mpz_init_set_str (a, argv[1], 10);
       mpz_init_set_str (b, argv[2], 10);
       /* Initialize p */
       mpz_init (p);


       /* compute the gcd of a and b*/
	mpz_gcd(p, a, b);

//     mp_size_t mpn_gcd (mp_limb_t *p, mp_limb_t *a,
//          mp_size_an, mp_limb_t *b, mp_size_t bn)

       /* Print p in base 10 */
	gmp_printf("%Zd\n", p);
//      mpz_out_str (stdout, 10, p);
//      fputc ('\n', stdout);

       /* Since we're about to exit, no need to clear out variables */
      return (0);
}
