lock_terminate(9r)lock_terminate(9r)NAMElock_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 ker‐
nel 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 variables
and in data structure members.
RETURN VALUES
None
