Press any key to continue ??

[Heals]

I need to read the instance of a keypress from the keyboard in linux or unix. I have used getchar() for the dos based compilers but I cannot find an eqivalent for the g++ compiler.

Is there such a function or do I have to construct my own. If so how is this done?

The easy way is to say 'Press return to continue'. getchar is buffered and is waiting for a CR before you get anything. The difficult way is to play with ioctl. There are so many options with ioctl, I wouldn't know how to advise you on it. If you call

ioctl( 0, FIONREAD, &numAvailable)

numAvailable will tell you how many chars have been pressed.

A getline should work, although a lot of compilers even getline won't read untill the enter is pressed.

string trash;
getline(cin, trash, 1);

Goodluck.
