curs_in_wch(3x)                                                curs_in_wch(3x)




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 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.
