I am writing an application in Microsoft QuickC, and I need, at some points, to blit a specified portion of video RAM (all four color planes) from one page of EGA video RAM to the other. QuickC has a routine that allows the copy of a specific screen area to RAM, then a recopy from RAM, and this will in fact work, but of course it means doing everything twice (once to RAM, once back to the alternate page). I have an assembly-language routine that will blit the entire EGA page to the other page, but I'd like to be able to do this (quickly) for limited areas. Does anyone happen to have a routine (in C, or easily accessible from C) that they'd be willing to share? Thanks. Ted A. Campbell tcamp@uncecs.edu
