getcchar(CURSES)
getcchar --
get a wide character string and rendition from a cchar_t
Synopsis
cc [options] file -lcurses
#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(CURSES)
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(CURSES)
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 application must provide a null pointer as opts.
Return value
When wch is a null pointer,
getcchar(CURSES)
returns the number of wide characters referenced by wcval,
including the null terminator.
When wch is not a null pointer,
getcchar(CURSES)
returns OK upon successful completion, and ERR otherwise.
Errors
No errors are defined.
Usage
The wcval argument may be a value generated by a call to
setcchar(CURSES)
or by a function that has a cchar_t output argument. If
wcval is constructed by any other means, the effect is unspecified.
Standards Conformance
The Single UNIX Specification, Version 2; The Open Group.
