Scan input - But only if something has been typed

[macuser55]

Hello all,

I would like to do a simple input scan from the command line, but only if
the user has typed something...

I have had a look at the select() method, but am still having trouble.

Basically, I want to treat stdin as a textField. Having a GUI would solve
this problem of course, but a gui is not required, and I'm after an easier
way.

Please read the C-FAQ.

Of course, select() not being part of ISO C.

Then you are off to the land of the Platform-specific. ISO C cannot do
what you require.

Alas, there's no way to do this in ISO standard C; you'll need platform
specific extensions.

HTH,

No need to do that: if your code need not be portable, there are
system specific solutions that are, usually, much simpler than
throwing in a GUI.
