curs_ins_wstr(3X) Library calls curs_ins_wstr(3X) NAME ins_wstr, ins_nwstr, wins_wstr, wins_nwstr, mvins_wstr, mvins_nwstr, mvwins_wstr, mvwins_nwstr - insert a wide-character string in a curses window SYNOPSIS #include <curses.h> int ins_wstr(const wchar_t *wstr); int ins_nwstr(const wchar_t *wstr, int n); int wins_wstr(WINDOW *win, const wchar_t *wstr); int wins_nwstr(WINDOW *win, const wchar_t *wstr, int n); int mvins_wstr(int y, int x, const wchar_t *wstr); int mvins_nwstr(int y, int x, const wchar_t *wstr, int n); int mvwins_wstr(WINDOW *win, int y, int x, const wchar_t *wstr); int mvwins_nwstr(WINDOW *win, int y, int x, const wchar_t *wstr, int n); DESCRIPTION These routines insert a wchar_t character string (as many characters as will fit on the line) before the character under the cursor, as if calling wins_wch(3X). All characters to the right of the cursor are shifted right, with the possibility of the rightmost characters on the line being lost. No wrapping is performed. The cursor position does not change (after moving to y, x, if speci- fied). The functions with n as the last argument insert a leading substring of at most n wchar_t characters. If n is less than zero, the entire string is inserted (stopping on a L'\0' character). Special characters are handled as in wadd_wch(3X). RETURN VALUE All functions return the integer ERR upon failure and OK on success. X/Open Curses does not specify any error conditions. This implementa- tion returns an error o if the win parameter is null or o if the wstr parameter is null or o if the wins_wch function returns an error. Functions prefixed with "mv" first perform cursor movement and fail if the position (y, x) is outside the window boundaries. NOTES All but wins_nwstr may be macros. If the first character in the string is a non-spacing character, these functions will fail. X/Open Curses does not define what will happen if a non-spacing character follows a control character. PORTABILITY These functions are described in X/Open Curses, Issue 4, which adds const qualifiers to the arguments. X/Open states that the entire string is inserted if n is less than 1. This is probably an error, because it is inconsistent with other func- tions, and differs from the X/Open implementation on Solaris.
