Question

linux gcc 4.4.1

I have the following fprintf statement and I would like to have the OK as green and the FAILED as red. Is this possible?

if(devh == -1)
{
    fprintf(stderr, "Device [ FAILED ]\n");
}
else
{
    fprintf(stderr, "Device [ OK ]\n");
}

Many thanks for any suggestions,

You should probably use some library such as ncurses to handle terminal.

Alternatively, under Linux you could use some console escape sequences such as:

printf ("\033[32;1m OK \033[0m\n");

(in this case 32 stands for green), but it is neither portable nor elegant.
