Additional Information
- SS.MpGPB maps a Get/Put buffer into the user address space. You can then save the buffer to disk or directly modify the pixel data contained in the buffer. Use extreme care when modifying the buffer so that you do not write outside of the buffer data area.
- The support modules for this call are GrfInt and WindInt.
