Loads annotations from a position within a file. This enables you to load an annotation file that is embedded in another file.
L_LTANN_API L_INT L_AnnLoadMultiOffset(fd, nOffset, nLength, phObjects, nCount, pnItemsRead, pLoadOptions)
The Windows file handle of the file to load.
The position, from the beginning of the file, of the first byte to load. (The byte count starts at zero.)
The number of bytes of annotation data to read from the file. If you saved the offset using L_AnnSaveMultiOffset, the variable pointed to by puSizeWritten in that function contains the length of data saved. If you do not know the length of the data, pass 0xFFFFFFFF for this parameter.
Pointer to an array that will receive the annotation container objects.
Size of the
Pointer to an L_INT that will receive the count of annotation containers successfully read.
Pointer to optional extended load options. Pass NULL because this parameter is currently ignored.

This function loads all pages of a multipage annotation file starting at a given offset, into an array. Each consecutive page of the multipage annotation file corresponds to one annotation container, and is loaded into consecutive slots of the array. If the annotation file contains many pages, then this method will load the multipage annotation file much faster than repeated calls to L_AnnLoad. Note that this function only loads annotation files that use the ANNFMT_XML format.
