I wrote a function to allocate memory to arrays of integers. But
it turns out that the the momory allocated was always at the same
location. What had I done improperly and how could I get around
the problem? (I use version 2 of the compiler.)

Thanks in advance.

#include <stdio.h>

void generateintvec(int *uh, int len)
{ free(uh);
   uh=calloc(len,sizeof(int));
   if (uh==NULL) printf("memmory allocation unsuccessful !!!\n");
}

int *vec1, *vec2;

int main()
{ generateintvec(vec1,30);
   generateintvec(vec2,30);
   if (vec1==vec2) printf("allocations were to the same location !!!\n");
   return(0);
}
