simple_lock_try(9r) simple_lock_try(9r)
NAME
simple_lock_try - General: Tries to assert a simple lock
SYNOPSIS
#include <kern/lock.h>
boolean_t simple_lock_try(
simple_lock_t slock_ptr );
ARGUMENTS
Specifies a pointer to a simple lock structure. You can declare this simple lock structure by using the decl_simple_lock_data routine.
DESCRIPTION
The simple_lock_try routine tries to assert a lock with read and write access for the resource associated with the specified simple lock.
The main difference between this routine and simple_lock is that simple_lock_try returns immediately if the resource is already locked,
while simple_lock spins until the lock has been obtained. Thus, call simple_lock_try when you need a simple lock but the code cannot spin
until the lock is obtained.
To release a simple lock successfully asserted by simple_lock_try, call the simple_unlock routine.
RETURN VALUES
The simple_lock_try routine returns one of the following values: The simple_lock_try routine successfully asserted the simple lock. The
simple_lock_try routine failed to assert the simple lock.
