SDL_UnlockRWLock

Unlock the read/write lock.

Header File

Syntax

void SDL_UnlockRWLock(SDL_RWLock *rwlock);

Function Parameters

SDL_RWLock *

rwlock

the rwlock to unlock.

Remarks

Use this function to unlock the rwlock, whether it was locked for read-only or write operations.

It is legal for the owning thread to lock an already-locked read-only lock. 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 rwlock").

It is illegal to unlock a rwlock that has not been locked by the current thread, and doing so results in undefined behavior.

Version

This function is available since SDL 3.1.3.
