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
FILES

Kernel routines: lock_done(9r), lock_init(9r), lock_try_read(9r), lock_try_write(9r), lock_write(9r)
