| X/Open Curses Library Functions | in_wch(3XCURSES) |
| | in_wch, mvin_wch, mvwin_wch, win_wch - retrieve a complex character (with rendition) |
SYNOPSIS
| |
#include <curses.h> int in_wch(cchar_t *wcval); |
| | int mvin_wch(int y, int x, cchar_t *wcval); |
| | int mvwin_wch(WINDOW *win, inty, cchar_t *wcval); |
| | int win_wch(WINDOW *win, cchar_t *wcval); |
| |
The in_wch() and win_wch() functions retrieve the complex character and its rendition located at the current cursor position of the stdscr
window and window win, respectively. The mvin_wch() and mvwin_wch() functions retrieve the complex character and its rendition located at
the position indicated by the x (column) and y (row) parameters (the former in the stdscr window; the latter in window win).
All these functions store the retrieved character and its rendition in the object pointed to by wcval.
