simple_lock_try

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.
