Win32: writing to STDOUT

[richardduncan]

I am developing a Win32 application with some basic command-line functionality; for example, the program has available a "--help" option that prints a brief help message then exits, without calling the GUI.

Clearly, using WRITE(UNIT=6,...) for writing to standard output does not work. When called from a regular WinXP "Command Prompt" terminal, e.g., "myprog.exe --help", nothing is printed in the terminal; however, when I redirect the output using

myprog.exe --help > help.out,

the file help.out is populated with the desired text. Furthermore, when executing "myprog --help" through a linux-emulator terminator (Cygwin), all works as expected.

Attempting to resolve this, I have tried using SetStdHandle; however, my implentation of this has been fruitless. Surely there is something fundamental here that I am missing.

Thanks a bunch,

Win32 apps don't have a console associated with them by default. You can create one by calling AllocConsole before you do the WRITE.

You may also want to consider using MessageBox to display the help text. Create a string with the text - embed CR-LF pairs as line separators, and terminate with a NUL.
