NAME

6       in_wch,  mvin_wch, mvwin_wch, win_wch - extract a complex character and
7       rendition from a window
8

SYNOPSIS

10       #include <curses.h>
11
12       int in_wch(cchar_t *wcval);
13       int win_wch(WINDOW *win, cchar_t *wcval);
14
15       int mvin_wch(int y, int x, cchar_t *wcval);
16       int mvwin_wch(WINDOW *win, int y, int x, cchar_t *wcval);
17

DESCRIPTION

19       These functions extract the complex character and  rendition  from  the
20       current position in the named window into the cchar_t object referenced
21       by wcval.
22

RETURN VALUE

24       No errors are defined in the XSI Curses standard.  This  implementation
25       checks  for null pointers, returns ERR in that case.  Also, the mv rou‐
26       tines check for error moving the cursor, returning ERR  in  that  case.
27       Otherwise they return OK.
28
29       Functions  with  a  “mv”  prefix  first perform a cursor movement using
30       wmove, and return an error if the position is outside the window, or if
31       the window pointer is null.
32

NOTES

34       Note that all of these routines may be macros.
