Syntax
#include <sys/lock_def.h>boolean_t lock_mine ( lock_addr)
void *lock_addr;
void *lock_addr;
Parameter
| Item | Description |
|---|---|
| lock_addr | Specifies the address of the lock word to check. |
Description
The lock_mine kernel service checks whether the specified simple or complex lock is owned by the calling kernel thread. Because a complex lock held in shared-read mode has no owner, the service returns FALSE in this case. This kernel service is provided to assist with debugging.
Execution Environment
The lock_mine kernel service can be called from the process environment only.
Return Values
| Item | Description |
|---|---|
| TRUE | Indicates that the calling kernel thread owns the lock. |
| FALSE | Indicates that the calling kernel thread does not own the lock, or that a complex lock is held in shared-read mode. |
