* 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 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.
*
* Portability X/Open BSD SYS V
