MapViewOfFile memory problem.

Hi,

    When calling MapViewOfFile (in winXP environment) repeatedly, Is it normal for the address of the return pointer to keep increasing?

E.g.

m_BmpBits = MapViewOfFile( m_MMFBmpBits, FILE_MAP_ALL_ACCESS, 0, 0, m_BmpSize);


The start address denoted by m_BmpBits keeps increasing when this line is executed repeatedly. When I check the memory usage of the application, it is increased with each iteration.

Do I need to free any memory?

Thanks.

You need to call UnmapViewOfFile(m_BmpBits) for each MapViewOfFile.
