| | td_ta_map_addr2sync - get a synchronization object handle from a synchronization object's address |
SYNOPSIS
| |
cc [ flag ... ] file ... -lthread_db [ library ... ]
#include <proc_service.h>
#include <thread_db.h> td_ta_map_addr2sync(const td_thragent_t *ta_p, psaddr_t addr,td_synchandle_t *sh_p); |
| |
td_ta_map_addr2sync() produces the synchronization object handle of type td_synchandle_t that corresponds to the address of the synchronization object (mutex,
semaphore, condition variable, or reader/writer lock). Some effort is made to validate addr and verify that it does indeed point at a synchronization object. The handle is returned in
*sh_p.
