Locks a specified lock object.
#include <prlock.h> void PR_Lock(PRLock *lock);
PR_Lock has one parameter:
- A pointer to a lock object to be locked.
PR_Lock returns, the calling thread is "in the monitor," also called "holding the monitor's lock." Any thread that attempts to acquire the same lock blocks until the holder of the lock exits the monitor. Acquiring the lock is not an interruptible operation, nor is there any timeout mechanism.
PR_Lock is not reentrant. Calling it twice on the same thread results in undefined behavior.
