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

for(;;)

is an infinite loop just like while(1). Here no condition is given that will terminate the loop. If you are not breaking it using break statement this loop will never come to an end.
