NAME

       simple_lock_init - General: Initializes a simple lock structure

SYNOPSIS

       #include <kern/lock.h>

       void simple_lock_init(
	       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_init routine initializes the simple lock structure that you previously declared with the decl_simple_lock_data routine. You
       need to initialize the simple lock structure only once. After you initialize the simple lock structure, you can call simple_lock to  assert
       exclusive access on the associated resource.

RETURN VALUES

       None
