insch(3NCURSES) 														   insch(3NCURSES)

NAME
insch, winsch, mvinsch, mvwinsch - insert a character before cursor in a curses window SYNOPSIS
#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); DESCRIPTION
These routines insert the character ch before the character under the cursor. All characters to the right of the cursor are moved one space to the right, with the possibility of the rightmost character on the line being lost. The insertion operation does not change the cursor position. RETURN VALUE
All routines that return an integer return ERR upon failure and OK (SVr4 specifies only "an integer value other than ERR") upon successful completion, unless otherwise noted in the preceding routine descriptions. Functions with a "mv" prefix first perform a cursor movement using wmove, and return an error if the position is outside the window, or if the window pointer is null. NOTES
These routines do not necessarily imply use of a hardware insert character feature. Note that insch, mvinsch, and mvwinsch may be macros. PORTABILITY
These functions are described in the XSI Curses standard, Issue 4. SEE ALSO
ncurses(3NCURSES). Comparable functions in the wide-character (ncursesw) library are described in ins_wch(3NCURSES). insch(3NCURSES)
