yes/no quastion about mutex

i have pretty simpel but importent quastion for my program

if i have many threads going trough one critical section of kode stopped by a mutex

when one thread is finish ready the critical section, and lets say 10 other threads are waiting to enter, will the threads enter the critical section in the same order they startet to wait? or will the thread enter the critical section randomly

thanks

It's called RTFM
"There is no guarantee about the order in which waiting threads will acquire ownership of the critical section."

oh ok - is there a command or way to create this queue ?
