td_thr_lockowner - iterate over the set of locks owned by a thread
cc [ flag... ] file... -lc_db [ library... ] #include <proc_service.h> #include <thread_db.h> td_err_e td_thr_lockowner(const td_thrhandle_t *th_p, td_sync_iter_f *cb, void *cb_data_p);
The td_thr_lockowner() function calls the iterator function cb once for every mutex that is held by the thread whose handle is th_p. The synchronization handle and the pointer cb_data_p are passed to the function. See td_ta_thr_iter(3C_DB) for a similarly structured function. Iteration terminates early if the callback function cb returns a non-zero value.
TD_OK The call completed successfully. TD_BADTH An invalid thread handle was passed in. TD_BADPH There is a NULL external process handle associated with this internal process handle. TD_DBERR A call to one of the imported interface routines failed. TD_ERR A libc_db internal error occurred.
