Detailed Description

Methods for managing locks on threads created.

Mutex lock class now just forwarding to std::mutex.

This method is obsolete. [From Maya 2020]

Deprecated:

Use std::mutex directly

Examples:

cvColorShader/cvColorShader.cpp, threadingLockTests/threadingLockTests.cpp, and threadTestWithLocksCmd/threadTestWithLocksCmd.cpp.

Constructor & Destructor Documentation

OPENMAYA_MAJOR_NAMESPACE_OPEN MMutexLock

(

)

Create new mutex object.

The object is created unlocked.

~MMutexLock

(

)

Calling the destructor on a locked mutex does not unlock the mutex.

That must be done by calling unlock() before calling the destructor.

Member Function Documentation

void lock

(

)

Create a lock.

If the mutex is available it is locked immediately. If it is already locked by another thread, this function waits until the other thread has unlocked it, then creates the lock.

Examples:

threadingLockTests/threadingLockTests.cpp.

bool tryLock

(

)

Attempt to lock the mutex.

If the mutex is already locked by another thread, the function returns right away.

Returns

• true lock was obtained
• false lock was not obtained
