You can use this function to traverse the TOC hierarchy in a depth-first fashion. Use the DtMmdbFreeHandleList function to release the memory when the object identifier is no longer needed. Table lookup is involved.ARGUMENTSrequest Specifies the bookcase in the bookcase descriptor field, as well as the id of the current section in the primary_oid field.RETURN VALUEIf DtMmdbDlpGetPrevSectionId completes successfully, it returns a pointer to the object identifier for the previous section or DtMmdbGroun- dId, if there is no previous section. If it fails, it returns a NULL pointer.EXAMPLEThe following shows how a DtMmdbDlpGetPrevSectionId call might be coded. DtMmdbInfoRequest request; /* fill the request here */ DtMmdbHandle* x = DtMmdbDlpGetPrevSectionId(&request); if ( x == DtMMdbGroundId) { /* no previous section */ } else { if (x == 0) { /* bad request */ } else { /* make use of x */ }SEE ALSODtMmdbDlpGetNextSectionId(3) DtMmdbDlpGetPrevSectionId(library call)
