Initializes a complex lock.
#include <sys/lock_def.h>
void lock_init ( lock_addr, can_sleep)
complex_lock_t lock_addr;
boolean_t can_sleep;
| lock_addr | Specifies the address of the lock word. |
| can_sleep | This parameter is ignored. |
The lock_init kernel service initializes the specified complex lock. This kernel service must be called for each complex lock before the lock is used. The complex lock must previously have been allocated with the lock_alloc kernel service. The can_sleep parameter is included for compatibility with OSF/1 1.1, but is ignored. Using a value of TRUE for this parameter will maintain OSF/1 1.1 semantics.
The lock_init kernel service can be called from the process environment only.
The lock_init kernel service has no return values.
The lock_alloc kernel service, lock_free kernel service.
