TStreamPos Class Reference
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.

Member Functions Documentation
Offset()
|
TInt
| Offset | ( | ) | const [inline] |
Gets the stream position value.
operator!=(TStreamPos)
Tests whether the stream position is not equal to the specified stream position.
Parameters
| TStreamPos aPos | The stream position to be compared. |
operator+(TInt)
Gets a stream position object that holds the result of adding the specified value to this object's stream position value.
Parameters
| TInt anOffset | The value to be added. |
operator+=(TInt)
Adds the specified value to this stream position object.
Parameters
| TInt anOffset | The value to be added. |
operator-(TStreamPos)
Gets the result of subtracting the specified stream position value from this object's stream position value.
Parameters
| TStreamPos aPos | The stream position whose value is to be subtracted. |
operator-(TInt)
Gets a stream position object that holds the result of subtracting the specified value from this object's stream position value.
Parameters
| TInt anOffset | The value to be subtracted. |
operator-=(TInt)
Subtracts the specified value from this stream position object.
Parameters
| TInt anOffset | The value to be subtracted. |
operator<(TStreamPos)
Tests whether the stream position is less than the specified stream position.
Parameters
| TStreamPos aPos | The stream position to be compared. |
operator<=(TStreamPos)
Tests whether the stream position is less than or equal to the specified stream position.
Parameters
| TStreamPos aPos | The stream position to be compared. |
operator==(TStreamPos)
Tests whether the stream position is equal to the specified stream position.
Parameters
| TStreamPos aPos | The stream position to be compared. |
operator>(TStreamPos)
Tests whether the stream position is greater than the specified stream position.
Parameters
| TStreamPos aPos | The stream position to be compared. |
operator>=(TStreamPos)
Tests whether the stream position is greater than or equal to the specified stream position.
Parameters
| TStreamPos aPos | The stream position to be compared. |
