lock_terminate

lock_terminate(9r)														lock_terminate(9r)

NAME

       lock_terminate - General: Terminates, using a complex lock

SYNOPSIS

       #include <kern/lock.h>

       void lock_terminate(
	       lock_t lock_structptr );

ARGUMENTS

       Specifies  a  pointer  to the complex lock structure, lock. The lock structure is an opaque data structure; that is, its associated members
       are referenced and manipulated by the operating system and not by the user of the complex lock mechanism.

DESCRIPTION

       The lock_terminate routine determines that the driver is done using the complex lock forever. The complex lock must be free (that  is,  the
       driver does not hold the lock) before calling lock_terminate. The kernel module must not reference the specified complex lock after calling
       lock_terminate.

NOTES

       You must call lock_init (once only) prior to calling lock_terminate to initialize the lock structure pointer for the resource.  A resource,
       from  the  kernel  module's standpoint, is data that more than one kernel thread can manipulate. You can store the resource in global vari-
       ables and in data structure members.

RETURN VALUES

       None
