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 *str);
int innwstr(wchar_t *str, int n);
int winwstr(WINDOW *win, wchar_t *str);
int winnwstr(WINDOW *win, wchar_t *str, int n);
int mvinwstr(int y, int x, wchar_t *str);
int mvinnwstr(int y, int x, wchar_t *str, int n);
int mvwinwstr(WINDOW *win, int y, int x, wchar_t *str);
int mvwinnwstr(WINDOW *win, int y, int x, wchar_t *str, int n);
DESCRIPTION
These routines return a string of wchar_t characters in wstr, extracted starting at the current cursor position in the named window.
Attributes are stripped from the characters. The four functions with n as the last argument return a leading substring at most n bytes
long (exclusive of the trailing NUL). Transfer stops at the end of the current line, or when n bytes have been stored at the location ref-
erenced by wstr.
If the size n is not large enough to store a complete character, an error is generated.
NOTES
Note that all routines except winnwstr may be macros.
RETURN VALUES
All routines return ERR upon failure. Upon successful completion, the *inwstr routines return OK, and the *innwstr routines return the num-
ber 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.
