NAME¶

SDL_CreateMutex - Create a new mutex.

SYNOPSIS¶

#include <SDL3/SDL_mutex.h>

SDL_Mutex * SDL_CreateMutex(void);

DESCRIPTION¶

All newly-created mutexes begin in the _unlocked_ state.

Calls to SDL_LockMutex() will not return while the mutex is locked by another thread. See SDL_TryLockMutex() to attempt to lock without blocking.

SDL mutexes are reentrant.

RETURN VALUE¶

Returns the initialized and unlocked mutex or NULL on failure; call SDL_GetError() for more information.

AVAILABILITY¶

This function is available since SDL 3.2.0.
