\fBtd_err_e\fR \fBtd_thr_lockowner\fR(\fBconst td_thrhandle_t *\fR\fIth_p\fR, \fBtd_sync_iter_f *\fR\fIcb\fR,

.SH DESCRIPTION
.sp
.LP
The \fBtd_thr_lockowner()\fR function calls the iterator function \fIcb\fR once for every mutex that is held by the thread whose handle is \fIth_p\fR. The synchronization handle and the pointer \fIcb_data_p\fR are passed to the function. See \fBtd_ta_thr_iter\fR(3C_DB) for a similarly structured function.
.sp
.LP
Iteration terminates early if the callback function \fIcb\fR returns a non-zero value.
