NAME

       SDL_RWLock - A mutex that allows read-only threads to run in parallel.

HEADER FILE

       Defined in SDL3/SDL_mutex.h

SYNOPSIS

       #include "SDL3/SDL.h"

       typedef struct SDL_RWLock SDL_RWLock;

DESCRIPTION

       A  rwlock  is roughly the same concept as SDL_Mutex , but allows threads that request read-only access to
       all hold the lock at the same time. If a thread requests write access, it will block until all  read-only
       threads  have released the lock, and no one else can hold the thread (for reading or writing) at the same
       time as the writing thread.

       This can be more efficient in cases where several threads need to access data frequently, but changes  to
       that data are rare.

       There  are other rules that apply to rwlocks that don't apply to mutexes, about how threads are scheduled
       and when they can be recursively locked.  These are documented in the other rwlock functions.

AVAILABILITY
