From: Tom White Subject: addressing specific extended memory with farptr module To: djgpp AT sun DOT soe DOT clarkson DOT edu Date: Mon, 18 Apr 1994 08:23:53 -0400 (EDT) First, thanks to those who directed me to the correct way to get onto this listserv. I am trying to do quick block transfers from a specific address in extended memory to vga video memory. I have ftped the farptr module from ftp.cygnus.com and I have spent most of the night looking through the docs trying to understand selectors, but there is little there and the examples always use the _go32_convential_mem_selector call. When I try using this selector and an offset of 0xF00000, the program crashes. So my two questions: How do I read from memory address F00000? And is the farptr stuff (using, say, _farnspeekl) the speedy way to do this or should I just use movedata? Thanks for any advice, -Tom -- =========================================================== Tom White white AT cs DOT uga DOT edu ===========================================================
