The upc_lock_free function

Synopsis

 
    #include <upc.h>
    upc_lock_t *upc_lock_free(upc_lock_t *ptr);                     

Description

The upc_lock_free function frees all resources associated with the dynamically allocated upc_lock_t pointed to by ptr. If ptr is a null pointer, no action occurs. Otherwise, if the argument does not match a pointer earlier returned by the upc_global_lock_alloc or upc_all_lock_alloc function, or if the lock has been deallocated by a previous call to upc_lock_free, the behavior is undefined.

upc_lock_free succeeds regardless of whether the referenced lock is currently unlocked or currently locked (by any thread).

Any subsequent calls to locking functions from any thread using ptr have undefined effects. This also applies to any thread currently calling upc_lock.
