.SH SYNOPSIS
\fB#include <curses.h>\fR
.sp
\fBint inchstr(chtype *chstr);\fR
.br
\fBint inchnstr(chtype *chstr, int n);\fR
.br
\fBint winchstr(WINDOW *win, chtype *chstr);\fR

.br

\fBint mvwinchnstr(WINDOW *win, int y, int x, chtype *chstr, int n);\fR

.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(3)].
.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
No error conditions are defined.
If the \fIchstr\fP parameter is null,
no data is returned,
and the return value is zero.
.SH NOTES
Note that all routines except \fBwinchnstr\fR may be macros.  SVr4 does not
document whether the result string is 0-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.
.SH SEE ALSO
\fBcurses\fR(3), \fBcurs_inch\fR(3).
.PP
Comparable functions in the wide-character (ncursesw) library are
described in
\fBcurs_in_wchstr\fR(3).
