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 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.
