_lock
Acquires a multi-thread lock.
void __cdecl _lock
int locknum
);
Parameters
- [in] locknum
The identifier of the lock to acquire.
Remarks
If the lock has already been acquired, this method acquires the lock anyway and causes an internal C run-time (CRT) error. If the method cannot acquire a lock, it exits with a fatal error and sets the error code to _RT_LOCK.
