Synopsis

APIRET APIENTRY KernAllocMutexLock(KEEMutexLock* ml);

Description

Initialize a mutexlock. This is basically the semaphore equivalent of a spinlock. Likewise, it is usable to protect critical regions. The difference to a spinlock is that waiting on a mutex will send the thread that processor is executing to sleep. This makes sense - in contrast to a spinlock - for longer critical regions.

Parameters

ml: Pointer to a mutexlock structure in 32 bit memory.
