CURSES_CCHAR(3) Library Functions Manual CURSES_CCHAR(3) NAME curses_cchar, getcchar, setcchar - curses representation of wide characters LIBRARY Curses Library (libcurses, -lcurses) SYNOPSIS #include <curses.h> int getcchar(const cchar_t *wcval, wchar_t *wch, attr_t *attrs, short *color_pair, void *opts); int setcchar(cchar_t *wcval, const wchar_t *wch, const attr_t attrs, short color_pair, const void *opts); DESCRIPTION Curses uses the opaque type cchar_t to represent a string of wide characters up to an implementation-dependent length along with a color pair and zero or more attributes. A null cchar_t object is an object that references an empty wide-character string. Arrays of cchar_t objects are terminated by a null cchar_t object. Objects of type cchar_t can be manipulated using the getcchar and setcchar functions. Both these functions take as their last parameter the opts argument which is reserved for future extensions. Currently, the application must provide a null pointer as opts. When the getcchar function is called with non-null wch it extracts the information from the wcval object. The string of wide characters in wcval is copied to the wch array. The attributes are stored in attrs and the color pair is stored in color_pair. In this case it returns OK upon successful completion, and ERR otherwise. When getcchar is called with null wch it doesn't store any information but returns the number of wide characters referenced by wcval, including the null terminator. setcchar initializes wcval with the wide-character string wch, attributes attrs, and color pair color_pair. RETURN VALUES getchar called with null wch returns the the number of wide characters referenced by wcval, including the null terminator. Otherwise these functions return one of the following values: OK The function completed successfully. ERR An error occurred in the function. STANDARDS The NetBSD Curses library complies with the X/Open Curses specification, part of the Single Unix Specification. HISTORY The Curses package appeared in 4.0BSD. Wide characters support appeared in NetBSD 5.0. NetBSD 8.99.34 November 19, 2018 NetBSD 8.99.34
