.SH DESCRIPTION
|
|
These routines return a NULL-terminated array of \fBchtype\fR quantities,
|
|
starting at the current cursor position in the named window and ending at the
|
|
right margin of the window.
|
|
The four functions with \fIn\fR as
|
|
the last argument, return a leading substring at most \fIn\fR characters long
|
|
(exclusive of the trailing (chtype)0).
|
|
Constants defined in \fB<curses.h>\fR can be used with the \fB&\fR (logical
|
|
AND) operator to extract the character or the attribute alone from any position
|
|
in the \fIchstr\fR [see \fBcurs_inch\fR(3X)].
|
|
.SH RETURN VALUE
|
|
All routines return the integer \fBERR\fR upon failure and an integer value
|
|
other than \fBERR\fR upon successful completion (the number of characters
|
|
retrieved, exclusive of the trailing 0).
|
|
.PP
|
|
X/Open Curses defines no error conditions.
|
|
In this implementation:
|
|
.bP
|
|
If the \fIwin\fP parameter is null, an error is returned,
|
|
.bP
|
|
If the \fIchstr\fP parameter is null, an error is returned,
|
|
.PP
|
|
Functions with a \*(``mv\*('' prefix first perform a cursor movement using
|
|
\fBwmove\fP, and return an error if the position is outside the window,
|
|
or if the window pointer is null.
|
|
.SH NOTES
|
|
Note that all routines except \fBwinchnstr\fR may be macros.
|
|
SVr4 does not
|
|
document whether the result string is zero-terminated; it does not document
|
|
whether a length limit argument includes any trailing 0; and it does not
|
|
document the meaning of the return value.
|
|
.SH PORTABILITY
|
|
These functions are described in the XSI Curses standard, Issue 4.
|
|
It is no
|
|
more specific than the SVr4 documentation on the trailing 0.
|
|
It does specify
|
|
that the successful return of the functions is \fBOK\fR.
|
|

|
|

.PP
|
|
Comparable functions in the wide-character (ncursesw) library are
|
|
described in
|
|
\fBcurs_in_wchstr\fR(3X).
