SDL_DestroyMutex

Destroy a mutex created with SDL_CreateMutex().

Header File

Syntax

void SDL_DestroyMutex(SDL_mutex * mutex);

Function Parameters

mutex

the mutex to destroy

Remarks

This function must be called on any mutex that is no longer needed. Failure to destroy a mutex will result in a system memory or resource leak. While it is safe to destroy a mutex that is unlocked, it is not safe to attempt to destroy a locked mutex, and may result in undefined behavior depending on the platform.

Version

This function is available since SDL 2.0.0.
