Hi,
I am writing a morse code converter and I am using the Beep() function in the windows header file to make the beep sounds, but I cannot seem to find an equivalent function for linux, man beep doesn't give me anything. Also a sleep function which allowed sleeping for only fractions of a second would be useful as the sleep function in linux doesn't accept decimals.
Thanks in advance,

To be very basic but very portable, you could always print a '\a'.
Or you could use ANSI escape sequences like this does. http://abcplus.sourceforge.net/beep.c
You could always use system("beep").
oh thanks, I thought that system() was windows only, that will come in handy.

The bare basics of the functionality of system() works on both *nix and Windows systems, however, there are problems with writing portable applications for both that use it. For example, to list the contents of a directory, it's ls vs dir.
Overall, I would recommend against using system() if you don't have to use it.
Yeah, I usually avoided it anyway, I am only using it for beep but I'll keep that in mind.
Does anyone know a sleep function which takes milliseconds for input in linux?

I don't think anything here will help: http://faq.cprogramming.com/cgi-bin/...&id=1043284392
Do a board search. I've never actually needed such a function, but usleep() comes to mind.
In accordance with MacGyver's advice I'll try and avoid using system("sleep") and try out those functions. The program will be linux/unix only anyway as it uses the c sockets library.

man usleep. it takes microseconds.Quote:
