Detailed Description

This class is just a simple wrapper for pthread_mutex_t. It does not provide any special logic for checking for correct usage, etc.

Member Function Documentation

lock()

DLLLOCAL void QoreThreadLock::lock ( )

no error checking happens here; if you grab the lock twice it will deadlock

trylock()

DLLLOCAL int QoreThreadLock::trylock ( )

inline

attempts to acquire the mutex and returns the status immediately; does not block

Returns

0 if the lock was acquired, a non-zero error number if the lock was not acquired
