NAME
SDL_LockMutex - Lock the mutex.
HEADER FILE
Defined in SDL3/SDL_mutex.h
SYNOPSIS
#include "SDL3/SDL.h"
void SDL_LockMutex(SDL_Mutex *mutex);
DESCRIPTION
This will block until the mutex is available, which is to say it is in the unlocked state and the OS has
chosen the caller as the next thread to lock it. Of all threads waiting to lock the mutex, only one may
do so at a time.
It is legal for the owning thread to lock an already-locked mutex. It must unlock it the same number of
times before it is actually made available for other threads in the system (this is known as a "recursive
mutex").
This function does not fail; if mutex is NULL, it will return immediately having locked nothing. If the
mutex is valid, this function will always block until it can lock the mutex, and return with it locked.
FUNCTION PARAMETERS
mutex the mutex to lock.
AVAILABILITY
This function is available since SDL 3.2.0.
