- get a synchronization object handle from a synchronization object's address
cc [ flag... ] file... -lc_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);
The td_ta_map_addr2sync() function 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.
The call completed successfully.
An invalid internal process handle was passed.
There is a NULL external process handle associated with this internal process handle.
The sh_p argument is NULL or addr does not appear to point to a valid synchronization object.
A call to one of the imported interface routines failed.
addr is NULL, or a libc_db internal error occurred.
