You can't??? I was under the impression that structure assignment was
already present even in K&R Classic. And gcc 2.95.2 -Wall -pedantic
has no qualms with a test program:


#include <stdio.h>
struct foo { int x, y; };
struct foo fn(int i, int j, int k);
int main(void)
{
struct foo result;
result = fn(3,1,4);
printf("result.x=%d result.y=%d\n", result.x, result.y);
return 0;
}
struct foo fn(int i, int j, int k)
{
struct foo s;
s.x = i+j+k;
s.y = i*j*k;
return s;
}
