NAMEDtMmdbGraphicGetData — obtains the data for a graphic object
SYNOPSIS
#include <DtMmdb.h>
const char* DtMmdbGraphicGetData(
DtMmdbInfoRequest* request,
unsigned int* length);
DESCRIPTION
The DtMmdbGraphicGetData function returns the data for a graphic
object. Do not use the free function on the returned pointer. Table
lookup is involved because the graphic identifier is specified by the
locator_ptr field.
ARGUMENTS
request Specifies the bookcase in the bookcase descriptor field and
the identifier of the graphic object in the locator_ptr
field.
length Specifies the variable to receive the length of the returned
data, if the returned pointer to the title is not NULL.
RETURN VALUE
If DtMmdbGraphicGetData completes successfully, it returns a pointer to
the data for the graphic object. If it fails, it returns a NULL
pointer.
EXAMPLE

DtMmdbInfoRequest request;
/* fill the request */
DtMmdbGraphicGetData(&request);
