I'm a newbie at DJGPP and was just wondering a few things.
1 - I see some programs written with DJGPP first run something called a
DOS
Extender?? When I write and compile a program in DJGPP is it
automatically
32 bit? If so, why do I not need to use a DOS Extender? Does my
program
automatically switch to protected mode transparently?
2 - Since it (DJGPP) requires a 386 or higher, should I assume that any
program compiled with it will not run on a 286? Also does this mean it
generates 386 instructions.
3 - If DJGPP uses 386 instructions, should I assume (that the same code
written
in DJGPP, and in Borlands Turbo C++ (Compiled in 286 mode). that DJGPP's
code will
run faster? Or is it only a small difference? Is it only noticably
quicker when
doing things like 32 bit memory transfers?
Thanks in advance to anyone who can help me!
Dave!
