NAME

       in_wch, mvin_wch, mvwin_wch, win_wch - get a curses complex character 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.
