SDL_LockMutex(3)

NAME
SDL_LockMutex - Lock the mutex.

SYNOPSIS
#include <SDL3/SDL_mutex.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.

THREAD SAFETY
It is safe to call this function from any thread.

AVAILABILITY
This function is available since SDL 3.2.0.
