NAME

SDL_WaitConditionTimeout - Wait until a condition variable is signaled or a certain time has passed.

HEADER FILE

Defined in SDL3/SDL_mutex.h

SYNOPSIS

#include "SDL3/SDL.h"

bool SDL_WaitConditionTimeout(SDL_Condition *cond,
SDL_Mutex *mutex, Sint32 timeoutMS);

DESCRIPTION

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

SDL_BroadcastCondition () on the condition variable cond , or for the specified time to elapse. Once the condition variable is signaled or the time elapsed, 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.

FUNCTION PARAMETERS

	cond		the condition variable to wait on.
	mutex		the mutex used to coordinate thread access.

timeoutMS

the maximum time to wait, in milliseconds, or -1 to wait indefinitely.

RETURN VALUE

Returns true if the condition variable is signaled, false if the condition is not signaled in the allotted time.

THREAD SAFETY

It is safe to call this function from any thread.

AVAILABILITY

This function is available since SDL 3.2.0.
