Name
       typeahead - check for typeahead

Syntax
       int typeahead(fd)
       int fd;

Description
       If is enabled, the program looks for typeahead input periodically while updating the screen.  If input is found, the current update will be
       postponed until or is called again.  This allows faster response to commands typed in advance.

       Normally, the input FILE pointer passed to the routine, will be used to do this typeahead checking.  If the routine was called,	the  input
       FILE pointer is passed to

       The routine specifies that the file descriptor is to be used to check for typeahead.  If is -1, then typeahead is disabled.

Return Values
       No return values are defined for this function.

Name
       prefresh, pnoutrefresh - refresh pad

Syntax
       #include <cursesX.h>

       int prefresh(pad, pminrow, pmincol, sminrow, smincol, smaxrow, smaxcol)
       WINDOW *pad;
       int pminrow, pmincol, sminrow, smincol, smaxrow, smaxcol;

       int pnoutrefresh(pad, pminrow, pmincol, sminrow, smincol, smaxrow, smaxcol)
       WINDOW *pad;
       int pminrow, pmincol, sminrow, smincol, smaxrow, smaxcol;

Description
       The routine copies the specified pad to the physical terminal screen.  It takes account of what is already displayed on the screen to opti-
       mize cursor movement.

       The routine copies the named pad to the virtual screen.	It then compares the virtual screen with the  physical	screen	and  performs  the
       actual update.

       These routines are analogous to the routines and except that pads, instead of windows, are involved.  Additional parameters are also needed
       to indicate what part of the pad and screen are involved.  The upper left corner of the part of the pad to be displayed is specified by and
       The co-ordinates and specify the edges of the screen rectangle that will contain the selected part of the pad.

       The  lower right corner of the pad rectangle to be displayed is calculated from the screen co-ordinates.  This ensures that the screen rec-
       tangle and the pad rectangle are the same size.

       Both rectangles must be entirely contained within their respective structures.

Return Values
       The and functions return OK on success and ERR on error.
