NAME
in_wch, mvin_wch, mvwin_wch, win_wch - extract a complex
character and rendition from a window
SYNOPSIS
#include <curses.h>
int in_wch(cchar_t *wcval);
int win_wch(WINDOW *win, cchar_t *wcval);
int mvin_wch(int y, int x, cchar_t *wcval);
int mvwin_wch(WINDOW *win, int y, int x, cchar_t *wcval);
DESCRIPTION
These functions extract the complex character and rendition from
the current position in the named window into the cchar_t object
referenced by wcval.
RETURN VALUE
No errors are defined in the XSI Curses standard. This
implementation checks for null pointers, returns ERR in that
case. Also, the mv routines check for error moving the cursor,
returning ERR in that case. Otherwise they return OK.
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
Note that all of these routines may be macros.
PORTABILITY
These functions are described in the XSI Curses standard, Issue
4.
