lock_clear_recursive Kernel Service


Prevents a complex lock from being acquired recursively.


#include <sys/lock_def.h>
void lock_clear_recursive (lock_addr)
complex_lock_t lock_addr;


lock_addr Specifies the address of the lock word which is no longer to be acquired recursively.


The lock_clear_recursive kernel service prevents the specified complex lock from being acquired recursively. The lock must have been made recursive with the lock_set_recursive kernel service. The calling thread must hold the specified complex lock in write-exclusive mode.

Execution Environment

The lock_clear_recursive kernel service can be called from the process environment only.

Return Values

The lock_clear_recursive kernel service has no return values.

Implementation Specifics

The lock_clear_recursive kernel service is part of the Base Operating System (BOS) Runtime.
