CURSES_ECHOCHAR(3) BSD Library Functions Manual CURSES_ECHOCHAR(3)
curses_echochar, echochar, wechochar, pechochar -- curses add characters
and then refresh routines
Curses Library (libcurses, -lcurses)
echochar(const chtype ch);
wechochar(WINDOW *win, const chtype ch);
pechochar(WINDOW *pad, const chtype ch);
These functions add characters to stdscr or to the specified window or
pad and then cause an immediate refresh() of that window or pad.
The echochar() function adds the character given in ch to stdscr at the
current cursor position and advances the current cursor position by one.
Any character attributes set in ch will be merged with the background
attributes currently set on stdscr. stdscr is then refreshed. Calling
echochar() is equivalent to calling addch() followed by refresh().
The wechochar() function is the same as the echochar() function, except-
ing that the character is added to the window specified by win and win is
The pechochar() function is the similar to the echochar() function,
excepting that the character is added to the pad specified by pad and pad
is refreshed at its previous location on the screen. Calling pechochar()
is equivalent to calling addch() followed by prefresh().
These functions will return one of the following values:
OK The function completed successfully.
ERR An error occurred in the function.
curses_addch(3), curses_attributes(3), curses_pad(3), curses_refresh(3)
The echochar(), wechochar(), and pechochar() functions comply with the
X/Open Curses specification, part of the Single Unix Specification.
The Curses package appeared in 4.0BSD.
