.SH DESCRIPTION
.sp
.LP
The \fBtd_ta_map_addr2sync()\fR function produces the synchronization object handle of type \fBtd_synchandle_t\fR that corresponds to the address of the synchronization object (mutex, semaphore, condition variable, or reader/writer lock). Some effort is made to validate \fIaddr\fR and verify that it does indeed point at a synchronization object. The handle is returned in *\fIsh_p\fR.
