One additional comment (and error on my part). Your function is suppose
to receive an integer, not a pointer to a structure.
if you intend to receive an integer in func() then you should code...
struct st { int c ; } ;
int func (b);
int b;
{
}
main()
{
struct st s;
func (s.c);
}
else if you intend to pass a pointer to the structure then you should code...
struct st { int c ; } ;
int func (b);
char *b;
{
}
main()
{
struct st s;
func (&s.c);
}
