SDL_TryLockMutex - Try to lock a mutex without blocking.

Defined in SDL3/SDL_mutex.h

#include "SDL3/SDL.h"

bool SDL_TryLockMutex(SDL_Mutex *mutex);

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.

mutex

the mutex to try to lock.

Returns true on success, false if the mutex would block.

This function is available since SDL 3.2.0.
