MSDN doesn't care which function comes from which DLL. It divides functions by their purpose, not by DLL they come from.

in that case where are command line functions documented? Things like print a line or something

As for "printing a line": at lowest level there is WriteFile function, that can write to standard output stream (it's handle is obtained by GetStdHandle). If you want to support console only, not any type of stream, then there is WriteConsole.

At higher level, there is standard C library which provides portability over operating system. You can look up "printf" or "print" or "put" from it.

By the way, calling these "command line functions" is not very precise naming...

You can use PETools program for listing names of all exported procedures.

I meant functions available when the program is in "console" mode (it's compiled with 'format PE console'. All I want is something similar to a list of system calls under a *nix

IIRC, the return value is in the EAX register.

All API functions are available in console mode. You can even call CreateWindow in a console app...

So what exactly is the difference?

it is just extra flag in executable, that causes windows to create console window for application (if there it isn't started from console already). That's all.

perhaps you need a complete example? (I'll try to post one if you need)

that would be brilliant.
strangely my first working windows app (that just exited) has stopped working.
Do you know where I could find a tutorial explaining how I need to change my Linux orientated assumptions about assembler (I know the obvious things like an API instead of system calls)
