Locks a specified lock object.
Syntax
#include <prlock.h> void PR_Lock(PRLock *lock);
Parameter
PR_Lock
has one parameter:
lock
- A pointer to a lock object to be locked.
Description
When 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.
