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
