SDL_DestroyMutex - Man Page

#include <SDL3/SDL_mutex.h>

void SDL_DestroyMutex(SDL_Mutex *mutex);

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.

This function is available since SDL 3.2.0.
