getstr, wgetstr, mvgetstr, mvwgetstr, wgetnstr - accept
character strings from curses terminal keyboard
int getstr(char *str);
int getnstr(char *str, int n);
int wgetstr(WINDOW *win, char *str);
int mvgetstr(int y, int x, char *str);
int mvwgetstr(WINDOW *win, int y, int x, char *str);
int mvgetnstr(int y, int x, char *str, int n);
int mvwgetnstr(WINDOW *, int y, int x, char *str, int n);
int wgetnstr(WINDOW *win, char *str, int n);
The function getstr is equivalent to a series of calls to
getch, until a newline or carriage return is received (the
terminating character is not included in the returned
string). The resulting value is placed in the area
pointed to by the character pointer str.
wgetnstr reads at most n characters, thus preventing a
possible overflow of the input buffer. Any attempt to
enter more characters (other than the terminating newline
or carriage return) causes a beep. Function keys also
cause a beep and are ignored. The getnstr function reads
from the stdscr default window.
The user's erase and kill characters are interpreted. If
keypad mode is on for the window, KEY_LEFT and
KEY_BACKSPACE are both considered equivalent to the user's
Characters input are echoed only if echo is currently on.
In that case, backspace is echoed as deletion of the pre-
vious character (typically a left motion).
All routines return the integer ERR upon failure and an OK
(SVr4 specifies only "an integer value other than ERR")
upon successful completion.
Note that getstr, mvgetstr, and mvwgetstr may be macros.
These functions are described in the XSI Curses standard,
Issue 4. They read single-byte characters only. The
standard specifies that they return ERR on failure, but
the single error condition EOVERFLOW associated with
extended-level conformance is not yet returned (the XSI
curses support for multi-byte characters is not yet
SVr3 and early SVr4 curses implementations did not reject
function keys; the SVr4.0 documentation claimed that "spe-
cial keys" (such as function keys, "home" key, "clear"
key, etc.) are interpreted" without giving details. It
lied. In fact, the `character' value appended to the
string by those implementations was predictable but not
useful (being, in fact, the low-order eight bits of the
key's KEY_ value).
The functions getnstr, mvgetnstr, and mvwgetnstr were pre-
sent but not documented in SVr4.
