As tabstop points out ... C cannot return arrays. It can return a struct, because it knows how big it is. (Well, actually it's returning a copy of a struct) Of course it can return a string in a struct...
Here's an example to demonstrate why you should never try to retun arrays from functions in C...
Code:
#include <stdio.h>
int* MyFunction(int a, int b, int c)
{ static int array[3];
array[0] = a;
array[1] = b;
array[2] = c;
return array; } // return a pointer.
int main (void)
{ int *a1, *a2; // int pointers
printf("calling a1 = MyFunction(10,20,30);\t");
a1 = MyFunction(10,20,30);
printf("a1 has %d %d %d\n",a1[0],a1[1],a1[2]);
printf("calling a2 = MyFunction(100,200,300);\t");
a2 = MyFunction(100,200,300);
printf("a2 has %d %d %d\n",a2[0],a2[1],a2[2]);
printf("\nLooks good, except...\t");
printf("a1 now has %d %d %d\n",a1[0],a1[1],a1[2]);
getchar();
return 0; }
Try it both with and without the static keyword...
