lock_init

lock_init(9r)															     lock_init(9r)

NAME

       lock_init - General: Initializes a complex lock

SYNOPSIS

       #include <kern/lock.h>

       void lock_init(
	       lock_t lock_structptr,
	       boolean_t can_sleep );

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.  Specifies a Boolean  value  that
       indicates  whether  to  allow kernel threads to block (sleep) if the complex lock is asserted. You can pass to this argument only the value
       TRUE (allow kernel threads to block if the lock is asserted).

DESCRIPTION

       The lock_init routine initializes a complex lock.  You identify this lock by declaring a pointer to a complex lock structure and passing it
       as  the	first argument. The complex lock structure pointer must be initialized before you can assert read and write operations on the com-
       plex lock.

RETURN VALUES

       None
