What kind of loop is for (;;)?

Question

Found in torvalds/linux-2.6.git -> kernel/mutex.c line 171

I have tried to find it on Google and such to no avail.

What does for (;;) instruct?<

Answer 1

It's an infinite loop that you'll have to break somehow from within using a break, return or goto statement. or either some interrupt happens otherwise this loop will run infinitely and executes ;(null statement) every time
