ANSI C: stdout in colors / sound / delay

[Olaf \El Blanco\]

I am working with gcc.
I would like to know:
* How can I put the stdout in differents colors.
(textcolor/background)
* I need different frequencies in sounds, and I only know the famous
printf ("\a");
* I need a function like Pascal delay(x)

Thank you!

Standard C will not help you here.

Depending on your terminal/output device you may be able to colorise
output using ANSI (am I right they're called that?) escape codes, which
you can emit using <stdio.h> functions. You'll have to look elsewhere
for what exactly is available.

Sounds will probably depend even more heavily on your particular OS, so
look for groups dealing with it.

Pretty much the same applies for timing. The only timer available in
standard C is from <time.h> and it only gives you the number of clock
ticks since your program started, but these may be affected by
multitasking and other OSy stuff.

Standard C has nothing useful for you. You have to use external
libraries, it depends on the OS, in a UNIX-like system search for
curses.

* I need a function like Pascal delay(x)

This is also system dependent, on UNIX systems there are two functions
called sleep() and usleep()

All these things are off-topic here, you should ask in
