NAME
in_wch, mvin_wch, mvwin_wch, win_wch - extract a complex character and
rendition from a window
SYNOPSIS
#include <ncurses/curses.h>
int in_wch(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);
int win_wch(WINDOW *win, 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 rou-
tines 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.
