SDL_TryLockRWLockForReading - Try to lock a read/write lock _for reading_ without blocking.
Defined in SDL3/SDL_mutex.h
#include "SDL3/SDL.h"
bool SDL_TryLockRWLockForReading(SDL_RWLock *rwlock);
This works just like
SDL_LockRWLockForReading (), but if the rwlock is not available, then this function returns false immediately.
This technique is useful if you need access to a resource but don't want to wait for it, and will return to it to try again later.
Trying to lock for read-only access can succeed if other threads are holding read-only locks, as this won't prevent access.
This function returns true if passed a NULL rwlock.
Returns true on success, false if the lock would block.
This function is available since SDL 3.2.0.
