.SH DESCRIPTION
|
|
The function \fBgetstr\fR is equivalent to a series of calls to \fBgetch\fR,
|
|
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 \fIstr\fR.
|
|
|
|
\fBwgetnstr\fR reads at most \fIn\fR 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 \fBgetnstr\fR function reads
|
|
from the \fIstdscr\fR default window.
|
|
|
|
The user's erase and kill characters are interpreted. If keypad
|
|
mode is on for the window, \fBKEY_LEFT\fR and \fBKEY_BACKSPACE\fR
|
|
are 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 left
|
|
motion).
|
|
.SH RETURN VALUE
|
|
All routines return the integer \fBERR\fR upon failure and an \fBOK\fR (SVr4
|
|
specifies only "an integer value other than \fBERR\fR") upon successful
|
|
completion.
|
|
.SH NOTES
|
|
Note that \fBgetstr\fR, \fBmvgetstr\fR, and \fBmvwgetstr\fR may be macros.
|
|
.SH PORTABILITY
|
|
These functions are described in the XSI Curses standard, Issue 4. They read
|
|
single-byte characters only. The standard specifies that they return \fBERR\fR
|
|
on failure, but the single error condition \fBEOVERFLOW\fR associated with
|
|
extended-level conformance is not yet returned (the XSI curses support for
|
|
multi-byte characters is not yet present).
|
|
|
|
SVr3 and early SVr4 curses implementations did not reject function keys;
|
|
the SVr4.0 documentation claimed that "special keys" (such as function
|
|
keys, "home" key, "clear" key, \fIetc\fR.) 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 \fBgetnstr\fR, \fBmvgetnstr\fR, and \fBmvwgetnstr\fR were
|
|
present but not documented in SVr4.
