NAME
ins_wch, mvins_wch, mvwins_wch, wins_wch - insert a complex character and rendition into a window SYNOPSIS
#include <curses.h> int ins_wch(const cchar_t *wch); int wins_wch(WINDOW *win, const cchar_t *wch); int mvins_wch(int y, int x, const cchar_t *wch); int mvwins_wch(WINDOW *win, int y, int x, const cchar_t *wch); DESCRIPTION
These routines, insert the complex character wch with rendition 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
If successful, these functions return OK. If not, they return ERR. 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. ERRORS
No errors are defined. SEE ALSO

curs_ins_wch, ins_wch, wins_wch, mvins_wch, mvwins_wch - Insert a complex character and rendition before the character under the cursor in a Curses window SYNOPSIS
#include <curses.h> int ins_wch( const cchar_t *wch ); int wins_wch( WINDOW *win, const cchar_t *wch ); int mvins_wch( int y, int x, const cchar_t *wch ); int mvwins_wch( WINDOW *win, int y, int x, const cchar_t *wch ); LIBRARY
Curses Library (libcurses) STANDARDS
Interfaces documented on this reference page conform to industry standards as follows: ins_wch, wins_wch, mvins_wch, mvwins_wch: XCURSES4.2 Refer to the standards(5) reference page for more information about industry standards and associated tags. DESCRIPTION
These functions insert the complex character wch, along with its rendition, in the current or specified window at the current or specified cursor position. These functions: Do not perform wrapping In other words, 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. Do not change the cursor position after moving to y, x, if specified This does not imply use of the hardware insert-character feature. Perform special-character processing NOTES
The header file <curses.h> automatically includes the header file <stdio.h>. Applications can use add_wch to add nonspacing characters to a spacing-complex character already in the window. Note that ins_wch, mvins_wch, and mvwins_wch may be macros. RETURN VALUES
