Small test function, please run on multiple systems, is it portable? Terminal $COLUMNS

I'm building a grid of OS support for telling an application what the terminal width is. Could you run this small test C program, and report results on various platforms? Is there a universal way to write a C program, to correctly get the terminal width, that will work across all environments that have consoles (e.g. Windows, cygwin, unix, linux, os x, BeOS, etc.)?Start Free Trial
