sdlTryLockMutex function mutex

bool sdlTryLockMutex(Pointer<NativeType> arg0, Pointer<NativeType> arg1)

Try to lock a mutex without blocking.

This works just like SDL_LockMutex(), but if the mutex is not available, this function returns false immediately.

This technique is useful if you need exclusive access to a resource but don't want to wait for it, and will return to it to try again later.

This function returns true if passed a NULL mutex.

\param mutex the mutex to try to lock. \returns true on success, false if the mutex would block.

\since This function is available since SDL 3.2.0.
