Description
       The  routine  reads  a  character from the terminal associated with the
       default window.

       The routine reads a character from the  terminal	 associated  with  the
       specified window.

       The  routine  reads  a  character from the terminal associated with the
       default window at the specified position.

       The routine reads a character from the  terminal	 associated  with  the
       specified window at the specified position.

       The  following  information  applies  to all the routines.  In mode, if
       there is no input waiting, the integer is returned.  In mode, the  pro‐
       gram  waits  until the system passes text through to the program.  Usu‐
       ally the program will restart after one character or  after  the	 first
       newline,	 but this depends on how is set.  The character will be echoed
       on the designated window unless has been set.

       If is and a function key is pressed, the token for that function key is
       returned	 instead  of  the  raw characters.  Possible function keys are
       defined in the header file with	integers  beginning  with  0401.   The
       function key names begin with KEY_.  Function keys and their respective
       integer values are described in the Guide to X/Open Curses  Screen-Han‐
       dling ®

       If  a  character	 is received that could be the beginning of a function
       key (such as escape), sets a timer.  If the remainder of	 the  sequence
       does  not come within the designated time, the character will be passed
       through, otherwise the function key value is  returned.	 Consequently,
       there  may  be  a  delay after a user presses the escape key before the
       escape is returned to the program.

       Using the escape key for a single character function is discouraged.

       The routines and are macros.

Return Values
       Upon successful completion, the	and  functions	return	the  character
       read.

       If in delay mode and no data is available, ERR is returned.
