SDL_WaitCondition - Man Page

Defined in SDL3/SDL_mutex.h

#include "SDL3/SDL.h"

void SDL_WaitCondition(SDL_Condition *cond, SDL_Mutex *mutex);

This function unlocks the specified mutex and waits for another thread to call SDL_SignalCondition () or

SDL_BroadcastCondition () on the condition variable cond . Once the condition variable is signaled, the mutex is re-locked and the function returns.

The mutex must be locked before calling this function. Locking the mutex recursively (more than once) is not supported and leads to undefined behavior.

This function is the equivalent of calling

SDL_WaitConditionTimeout () with a time length of -1.

cond

the condition variable to wait on.

mutex

the mutex used to coordinate thread access.

It is safe to call this function from any thread.

This function is available since SDL 3.2.0.
