Question

My friends tell me that a special loop exists that isn’t a ‘while’ loop or a ‘do while’ loop.

Does anyone know what it’s called and the correct syntax for it’s use?

Answer 1

A setjmp loop perhaps? That is pretty special.

static jmp_buf buf;

int i = 0;
if ( setjmp(buf) < end ) {
    /* do stuff */
    longjmp(buf, i++);
}
