How to read a character from stdin without the program wait for aEnter key?

[eap.britzkrieg]

Hello,

I wanna read characters from stdin as long as I put them on it from
keyboard.

For example:

If I use

fscanf(stdin, "%c", &c);

when I put 'w', for instance, fscanf() waits until I press Enter, but
I don't wanna that this occur.

If I press 'w', I wanna that the program uses 'w' immediately.

Thanks a lot.

You need a function that is specific to your OS. (Using Windows console,
it's getch(), defined in conio.h. This might save you wading through the faq
mentioned elsewhere, which seems a little dated.)

A more portable solution would be ncurses, which is available for most
*nixes and also MS Windows.
