What is this called and how is it possible?
switch (state_in->step){
while (1){
case step_a:
// do something and fallthrough
case step_b:
// do something and fallthrough
case step_c:
// do something and fallthrough
case step_d:
// do something and fallthrough
}
}
snippet is from cdecode.c of the libb64 project. The state_in->step variable is not touched inside the loop, and code seems to iterate step_a->step_b->step_c->step_d->step_a->....
It seems as if switch acts as a smart goto statement, pointing inside a while loop? I would like to know how this thing works, but google only gives me switch inside a loop in C.
