### Synopsis

    int instr(char *str);
    int innstr(char *str, int n);
    int winstr(WINDOW *win, char *str);
    int winnstr(WINDOW *win, char *str, int n);
    int mvinstr(int y, int x, char *str);
    int mvinnstr(int y, int x, char *str, int n);
    int mvwinstr(WINDOW *win, int y, int x, char *str);
    int mvwinnstr(WINDOW *win, int y, int x, char *str, int n);

    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 functions take characters (or wide characters) from the
   current or specified position in the window, and return them as
   a string in str (or wstr). Attributes are ignored. The functions
   with n as the last argument return a string at most n characters
   long.

### Return Value

   Upon successful completion, innstr(), mvinnstr(), mvwinnstr()
   and winnstr() return the number of characters actually read into
   the string; instr(), mvinstr(), mvwinstr() and winstr() return
   OK. Otherwise, all these functions return ERR.
