#include <curses.h> int add_wch(const cchar_t *wch); int wadd_wch(WINDOW *win, const cchar_t *wch); int mvadd_wch(int y, int x, const cchar_t *wch); int mvwadd_wch(WINDOW *win, int y, int x, const cchar_t *wch);
These functions add information to the current or specified window at the current or specified position, and then advance the cursor. These functions perform wrapping. These functions perform special-character processing.
- If wch refers to a spacing character, then any previous character at that location is removed, a new character specified by wch is placed at that location with rendition specified by wch; then the cursor advances to the next spacing character on the screen.
- If wch refers to a non-spacing character, all previous characters at that location are preserved, the non-spacing characters of wch are added to the spacing complex character, and the rendition specified by wch is ignored.
Upon successful completion, these functions return OK. Otherwise, they return ERR.
No errors are defined.
