Does anyone know what the hell #pragma means?? I looked it up in C++ help, but I have v4, so it may be a new thing... ============================== \\// live long and prosper; \||/ die short and rot. ==============================

#pragma''s are compiler-specific things, which control how the source code is compiled.

For example, with VC 6 you can use #pragma''s to control the packing of structures, disable specific warnings, or disable optimizations for a specific function.

More info on pragma in VC 6 is at http://msdn.microsoft.com.

mhkrause is right

and for example you can use pragma for inlude library files :
#pragma comment (lib, "ddraw.lib") and so on

Another example: In the Watcom compiler, you used "#pragma aux" to do inline assembly.

The important thing about #pragma''s is that they won''t break your compile. For example:

#pragma this is a stupid pragma

If the compiler doesn''t recognize the #pragma (and in this case its fairly unlikely that it will) it will just ignore it.


I guess this is where most people put a famous quote...

Thanks everyone - now if I can just ask you to go one step further and try and Identofy these:

1 - #pragma pack(push)
2 - #pragma pack(1)
3 - #pragma pack(pop)

thanks.

Push the current pack state onto a stack, set the pack state to byte align, and then pop the original pack state back.

You can also use it to block multiple includes, so instead of

#ifndef SOMETHING_H
#define SOMETHING_H

//blah blah

#endif

you can use:

#pragma once
