far void()

[khaleel.alyasini@gmail.com]

hi, i would like to know if i want to use something like this ..


far void functionA()
{
process;
}

but the problem is .. C++ or should i say VC++ doesnt recognize the
'far' function. does anyone know what header file should be included?

There is no such thing as "far" in standard C++. Some implementations might
have something like that, but you would need to ask in a newsgroup about
VC++ to find out if that one has it (and how or why to use it).
comp.lang.c++ only deals with standard C++.

Re: far void()

Hi,

In windows apps there is no need to use far. In the 'far' past we used to
use far to distinquish pointers and calls in between segments i.e. normally
you could only address 64kB The part in memory was determined by the value
in DS, CS etc.(the segment registers). However luckily those days are gone.
The memroy is now 'flat' meaning there is no tiny, small medium far and huge
pointers etc. There is just 32 bits windows (until 64 becomes common).

far is not a function, it is probably a macro, it goes back to the days of
DOS when RAM was in 64KB chunks, called segments. The modern way to write
the function above is simply to drop the "far" so it becomes:

void functionA() { }.

If you are trying to use an old library you probably should try to find an
old compiler to go with the old library. Borland offers such a compiler
for free and perhaps Microsoft does too.

Good old Turbo C and C++ for DOS. I remember well.

If there are a lot, then a new macro can be created, but it's really
better to weed them out if possible. The bigger problem is that code
using them is likely outdated in many other ways, and probably should
be extensively rewritten anyway.
