[Daniel G. <sp...@ho...>]

Do you need conio_mingw.h  for all these to work? Wouldn't <conio.h> do?

[Dev-C++] What is the scope of preprocessor directives???

[David M. <ci...@ya...>]

What is the scope of a preprocessor directive?

For example if I put a #define what statements are affected by it?

Also if I have a *.h file that has a set of #defines in it will they 
affect other files in the project or am I restricted to the command
line for that

The scope of the rest of its file and the files in which its file is
included. Or till one other directive that cancels it.

Yes they can if you #include the file in other files. But you must try
hardly to not happen that. So use large & ugly names for macros and if
possible #undef them at the end of their use.
