I am aware that there is this header file named conio.h that works with functions like getche() . This header is not included in my linux OS (Redhat 7.0). Is there an equivalent header that does the same thing with the gcc library of headers, or is there a place to obtain a copy of the library file?
There is no same header file under Linux, but you sure do have a similar library called the 'curses' library. You do have the getch() function in it as well. If you have installed it on your machin, you can use it. See help on curses, man curses
