DtMmdbSectionGetBookId(library call) DtMmdbSectionGetBookId(library call)
NAMEDtMmdbSectionGetBookId — obtains the object identifier of a book
SYNOPSIS
#include <DtMmdb.h>
DtMmdbHandle* DtMmdbSectionGetBookId(
DtMmdbInfoRequest* request);
DESCRIPTION
The DtMmdbSectionGetBookId function returns the object identifier of
the book that contains the specified section. Use the DtMmdbFreeHandle
function to release the identifier when it is no longer needed. Table
lookup is involved if the section identifier is specified by the loca‐
tor_ptr field.
ARGUMENTS
request Specifies the bookcase in the bookcase descriptor field and
either the section's Database Engine identifier (in the pri‐
mary_oid field) or the section's logical identifier (in the
locator_ptr field). If both of these fields have a value,
DtMmdbSectionGetBookId uses the locator_ptr value.
RETURN VALUE
If DtMmdbSectionGetBookId completes successfully, it returns a pointer
to the book's object identifier. If it fails, it returns a NULL
pointer.

The following shows how a DtMmdbSectionGetBookId call might be coded.
