DtMmdbSectionGetLoc(library call) DtMmdbSectionGetLoc(library call)
NAMEDtMmdbSectionGetLoc — obtains a section's locator
SYNOPSIS
#include <DtMmdb.h>
const char* DtMmdbSectionGetLoc(
DtMmdbInfoRequest* request);
DESCRIPTION
The DtMmdbSectionGetLoc function returns the logical identifier for the
specified section. Do not use the free function on the returned
pointer. No table lookup is involved.
The space used by the returned locator pointer is likely to be reused
by the database engine when any of the API functions are invoked again.
You must make a copy of the content if you want to retain it across
multiple API calls. This behavior holds true for all functions that
return a const char* pointer.
ARGUMENTS
request Specifies the bookcase in the bookcase descriptor field and
the section's Database Engine (object) identifier in the pri‐
mary_oid field. The DtInfo Database Engine identifier is
assigned to the section when it is stored.
RETURN VALUE
If DtMmdbSectionGetLoc completes successfully, it returns a pointer to
a NULL-terminated locator string. If it fails, it returns a NULL
pointer.
EXAMPLE
The following shows how a DtMmdbSectionGetLoc call might be coded.
const char* locator = 0;
DtMmdbInfoRequest request;
int bd = DtMmdbGetBookCase(myInfoLibPtr, "myBase");
if ( bd >= 0) {
request.bookcase_descriptor = bd;
request.sequence_num = 1;
request.primary_oid = DtMmdbBookGetTocObjectId(&request);
locator = DtMmdbSectionGetLoc(&request);
}
