SDL_TryLockRWLockForReading(3) | SDL3 FUNCTIONS | SDL_TryLockRWLockForReading(3) |
NAME¶
SDL_TryLockRWLockForReading - Try to lock a read/write lock _for reading_ without blocking.
SYNOPSIS¶
#include <SDL3/SDL_mutex.h>
bool SDL_TryLockRWLockForReading(SDL_RWLock *rwlock);
DESCRIPTION¶
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.
FUNCTION PARAMETERS¶
- rwlock
- the rwlock to try to lock.
RETURN VALUE¶
Returns true on success, false if the lock would block.
AVAILABILITY¶
This function is available since SDL 3.2.0.
