|
|
<P>The <CODE>conio.h</CODE> header file contains a large set of functions that do screen
|
|
and keyboard I/O. The functions will write directly to the screen or poll the
|
|
keyboard directly with no more help from the operating system than needed.
|
|
This has some disadvantages, but on the other side it's fast and reasonably
|
|
portable. conio implementations exist for the following targets:</P>

<P>The conio.h header file does also include the system specific header files
|

which define constants for special characters and keys.</P>
