inwstr, innwstr, winwstr, winnwstr, mvinwstr, mvinnwstr, mvwinwstr,
mvwinnwstr - get a string of wchar_t characters from a curses window
#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);
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 sub-
string 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 charac-
ter, an error is generated.
All routines except winnwstr may be macros.
Each cell in the window holds a complex character (i.e., base- and com-
bining-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.
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.
