_lock

Acquires a multi-thread lock.

Important

This function is obsolete. Beginning in Visual Studio 2015, it is not available in the CRT.

Syntax

void __cdecl _lock(
   int locknum
);

Parameters

locknum
[in] 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 can't acquire a lock, it exits with a fatal error and sets the error code to _RT_LOCK.

Requirements
