CURSES_INSCH(3) Library Functions Manual CURSES_INSCH(3)

curses_insch, insch, winsch, mvinsch, mvwinsch
curses insert characters routines

Curses Library (libcurses, -lcurses)

#include <curses.h>

int
insch(chtype ch);

int
winsch(WINDOW *win, chtype ch);

int
mvinsch(int y, int x, chtype ch);

int
mvwinsch(WINDOW *win, int y, int x, chtype ch);

These functions insert characters on stdscr or on the specified window.

The insch() function inserts the character given in ch at the current cursor position on stdscr. The cursor is not advanced and wrapping is not performed.

The winsch() function is the same as the insch() function, excepting that the character is inserted on the window specified by win.

The mvinsch() and mvwinsch() functions are the same as the insch() and insch() functions, respectively, excepting that wmove() is called to move the cursor to the position specified by y, x before the character is inserted on the window.

Functions returning pointers will return NULL if an error is detected. The functions that return an int will return one of the following values:

OK
The function completed successfully.
ERR
An error occurred in the function.
