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 mvin_wch(int y, int x, cchar_t *wcval);
14       int mvwin_wch(WINDOW *win, int y, int x, cchar_t *wcval);
15       int win_wch(WINDOW *win, cchar_t *wcval);
16

DESCRIPTION

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

RETURN VALUE

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

NOTES

33       Note that all of these routines may be macros.
