The resulting value is placed in thearea pointed to by the character pointer \fIstr\fR.\fBwgetnstr\fR reads at most \fIn\fR characters, thus preventing a possibleoverflow of the input buffer.  Any attempt to enter more characters (otherthan the terminating newline or carriage return) causes a beep.  Functionkeys also cause a beep and are ignored.  The \fBgetnstr\fR function readsfrom the \fIstdscr\fR default window.The user's erase and kill characters are interpreted.  If keypadmode is on for the window, \fBKEY_LEFT\fR and \fBKEY_BACKSPACE\fRare both considered equivalent to the user's kill character.Characters input are echoed only if \fBecho\fR is currently on.  In that case,backspace is echoed as deletion of the previous character (typically a leftmotion)..SH RETURN VALUEAll routines return the integer \fBERR\fR upon failure and an \fBOK\fR (SVr4specifies only "an integer value other than \fBERR\fR") upon successfulcompletion..SH NOTESNote that \fBgetstr\fR, \fBmvgetstr\fR, and \fBmvwgetstr\fR may be macros..SH PORTABILITYThese functions are described in the XSI Curses standard, Issue 4.They read single-byte characters only.The standard does not define any error conditions.This implementation returns ERR if the window pointer is null,or if the lower-level \fBwgetch\fR call returns an ERR.SVr3 and early SVr4 curses implementations did not reject function keys;the SVr4.0 documentation claimed that "special keys" (such as functionkeys, "home" key, "clear" key, \fIetc\fR.) are "interpreted", withoutgiving details.  It lied.  In fact, the `character' value appended to thestring by those implementations was predictable but not useful(being, in fact, the low-order eight bits of the key's KEY_ value).The functions \fBgetnstr\fR, \fBmvgetnstr\fR, and \fBmvwgetnstr\fR werepresent but not documented in SVr4..SH SEE ALSO\fBcurses\fR(3X), \fBcurs_getch\fR(3X)..\"#.\"# The following sets edit modes for GNU EMACS.\"# Local Variables:.\"# mode:nroff.\"# fill-column:79.\"# End:
