GETCCHAR(3XCURSES) X/Open Curses Library Functions GETCCHAR(3XCURSES)

NAME

getcchar - get a wide character string (with rendition) from a
cchar_t

SYNOPSIS

cc [ flag... ] file... -I /usr/xpg4/include -L /usr/xpg4/lib \
-R /usr/xpg4/lib -lcurses [ library... ]

c89 [ flag... ] file... -lcurses [ library... ]

#include <curses.h>

int getcchar(const cchar_t *wcval, wchar_t *wch, attr_t *attrs,
short *color_pair,void *opt);

DESCRIPTION

If wch is not a null pointer, the getcchar() function splits the
cchar_t object pointed to by wcval into a wide character string,
attributes, and a color pair. It stores the attributes in the
location pointed to by attrs, the color pair in the location pointed
to by color_pair, and the wide character string in the location
pointed to by wch.

If wch is a null pointer, the getcchar() function simply returns the
number of wide characters in the cchar_t object pointed to by wcval.
The objects pointed to by attrs and color_pair are not changed.

PARAMETERS

wcval
Is a pointer to a cchar_t object.

wch
Is a pointer to an object where a wide character string
can be stored.

attrs
Is a pointer to an object where attributes can be
stored.

color_pair
Is a pointer to an object where a color pair can be
stored.

opts
Is reserved for future use. Currently, this must be a
null pointer.

RETURN VALUES

When wch is a null pointer, the getcchar() function returns the
number of wide characters in the string pointed to by wcval including
the null terminator.

When wch is not a null pointer, the getcchar() function returns OK
on success and ERR otherwise.

ERRORS

None
