NAME

getcchar — get a wide character string and rendition from a cchar_t

SYNOPSIS

#include <curses.h>

int getcchar(const cchar_t *wcval, wchar_t *wch, attr_t *attrs,

short *color_pair, void *opts);

DESCRIPTION

When wch is not a null pointer, the

getcchar() function extracts information from a cchar_t deﬁned

by wcval, stores the character attributes in the object pointed to by attrs, stores the colour pair in the

object pointed to by color_pair, and stores the wide character string referenced by wcval into the array

pointed to by wch.

When wch is a null pointer,

getcchar() obtains the number of wide characters in the object pointed to

by wcval and does not change the objects pointed to by attrs or color_pair.

The opts argument is reserved for deﬁnition in a future edition of this document. Currently, the applica-

tion must provide a null pointer as opts.

RETURN VALUE

When wch is a null pointer,

getcchar() returns the number of wide characters referenced by wcval,

including the null terminator.

When wch is not a null pointer,

getcchar() returns OK upon successful completion, and ERR other-

wise.

ERRORS

No errors are deﬁned.

APPLICATION USAGE

The wcval argument may be a value generated by a call to

setcchar() or by a function that has a

cchar_t output argument. If wcval is constructed by any other means, the effect is unspeciﬁed.
