What type is being returned? If you meant "nothing", specify void.

As per last reply, I want to return a string, but am not sure of the
syntax for returning arrays...

You can't return an array, but you can return a pointer to the first
entry.


#include <stdio.h>
#include <string.h>
#define MAX_LENGTH 256

char * foo(void)
{
static char ret[MAX_LENGTH];
strncpy(ret, "test", MAX_LENGTH);
return ret;
}

int main(void)
{
printf("%s\n", foo());
return 0;
}

.
