NAME

       inwstr, innwstr, winwstr, winnwstr, mvinwstr, mvinnwstr, mvwinwstr,
       mvwinnwstr - get a string of wchar_t characters from a curses window


SYNOPSIS

       #include <curses.h>

       int inwstr(wchar_t *wstr);
       int innwstr(wchar_t *wstr, int n);
       int winwstr(WINDOW *win, wchar_t *wstr);
       int winnwstr(WINDOW *win, wchar_t *wstr, int n);

       int mvinwstr(int y, int x, wchar_t *wstr);
       int mvinnwstr(int y, int x, wchar_t *wstr, int n);
       int mvwinwstr(WINDOW *win, int y, int x, wchar_t *wstr);
       int mvwinnwstr(WINDOW *win, int y, int x, wchar_t *wstr, int n);


DESCRIPTION

       These routines return a string of wchar_t wide characters in wstr,
       extracted starting at the current cursor position in the named window.

       The four functions with n as the last argument return a leading substring
       at most n characters long (exclusive of the trailing NUL).  Transfer
       stops at the end of the current line, or when n characters have been
       stored at the location referenced by wstr.

       If the size n is not large enough to store a complete complex character,
       an error is generated.


NOTES

       All routines except winnwstr may be macros.

       Each cell in the window holds a complex character (i.e., base- and
       combining-characters) together with attributes and color.  These
       functions store only the wide characters, ignoring attributes and color.
       Use in_wchstr to return the complex characters from a window.


RETURN VALUE

       All routines return ERR upon failure.  Upon successful completion, the
       *inwstr routines return OK, and the *innwstr routines return the number
       of characters read into the string.

       Functions with a "mv" prefix first perform a cursor movement using wmove,
       and return an error if the position is outside the window, or if the
       window pointer is null.
