Name

td_thr_lockowner - iterate over the set of locks owned by a thread

Synopsis

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);

Description

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.

Return Values

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.
