Wait for a lock to be available.

This function may be called in a request that fails to acquire a desired lock. This will block further execution until the lock is available or the specified delay in seconds is reached. This should not be used with locks that are acquired very frequently, since the lock is likely to be acquired again by a different request while waiting.

Parameters

string $name: The name of the lock.

int $delay: The maximum number of seconds to wait, as an integer.

Return value

bool TRUE if the lock holds, FALSE if it is available.
