SYNOPSIS


#include <curses.h>

int in_wchstr(cchar_t *wchstr);


int in_wchnstr(cchar_t *wchstr, int n);


int win_wchstr(WINDOW *win, cchar_t *wchstr);


int win_wchnstr(WINDOW *win, cchar_t *wchstr, int n);


int mvin_wchstr(int y, int x, cchar_t *wchstr);


int mvin_wchnstr(int y, int x, cchar_t *wchstr, int n);


int mvwin_wchstr(WINDOW *win, int y, int x, cchar_t *wchstr);


int mvwin_wchnstr(WINDOW *win, int y, int x, cchar_t *wchstr, int n);

 

DESCRIPTION

These functions return an array of complex characters in wchstr,
starting at the current cursor position in the named window.
Attributes (rendition) are stored with the characters.

The
in_wchnstr,
mvin_wchnstr,
mvwin_wchnstr
and
win_wchnstr
fill the array
with at most
n
cchar_t
elements.

 

NOTES

Note that all routines except
win_wchnstr
may be
macros.

Reading a line that overflows the array pointed to by
wchstr
with
in_wchstr,
mvin_wchstr,
mvwin_wchstr
or
win_wchstr
causes undefined results. Therefore, the use of
in_wchnstr,
mvin_wchnstr,
mvwin_wchnstr, or
win_wchnstr
is recommended.
 

RETURN VALUES

Upon successful completion, these functions return
OK.
Otherwise, they return
ERR.
 

PORTABILITY

The XSI Curses defines no error conditions.
This implementation checks for null pointers,
returning ERR in that case.
