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. Usually 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-Handling (R)
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. Conse-
quently, 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.
