Function SDL_TryLockRWLockForReading 

pub unsafe extern "C" fn SDL_TryLockRWLockForReading(
    rwlock: *mut SDL_RWLock,
) -> bool

Try to lock a read/write lock for reading without blocking.

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.

Parameter: rwlock the rwlock to try to lock. Returns: true on success, false if the lock would block.

Thread Safety: It is safe to call this function from any thread.

Available Since: This function is available since SDL 3.2.0.
