| class TStreamPos |
Holds the position of the read or write mark within a seekable stream.
Position is the offset from the beginning of a seekable stream. The class provides convenient operators for performing arithmetic on the offset value and for doing comparisons between stream position objects.
It can be considered as an absolute stream position.
Objects of this type are usually created as a result of calling MStreamBuf::SeekL() or MStreamBuf::TellL(); they allow a program to remember the current read position in a stream buffer and reset it to the same location later.
