+.SH NAME
+\fBinch\fP,
+\fBwinch\fP,
+\fBmvinch\fP,
+\fBmvwinch\fP \- get a character and attributes from a \fBcurses\fP window
+.SH SYNOPSIS
+\fB#include <curses.h>\fP
+.sp
+\fBchtype inch(void);\fP
+.br
+\fBchtype winch(WINDOW *\fIwin\fB);\fR
+.sp
+\fBchtype mvinch(int \fIy\fB, int \fIx\fB);\fR
+.br
+\fBchtype mvwinch(WINDOW *\fIwin\fB, int \fIy\fB, int \fIx\fB);\fR
+.br
+.SH DESCRIPTION
+These routines return the character, of type \fBchtype\fP, at the current
+position in the named window.
+If any attributes are set for that position,
+their values are OR'ed into the value returned.
+Constants defined in
+\fB<curses.h>\fP can be used with the \fB&\fP (logical AND) operator to
+extract the character or attributes alone.
+.
+.SS Attributes
+The following bit-masks may be AND-ed with characters returned by \fBwinch\fP.
+.
+.TS
+l l .
+\fBA_CHARTEXT\fP	Bit-mask to extract character
+\fBA_ATTRIBUTES\fP	Bit-mask to extract attributes
+\fBA_COLOR\fP	Bit-mask to extract color-pair field information
+.TE
+.SH RETURN VALUE
+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.
+.PP
+The \fBwinch\fP function does not return an error if the window contains
+characters larger than 8-bits (255).
+Only the low-order 8 bits of the character are used by \fBwinch\fP.
+.SH NOTES
+Note that all of these routines may be macros.
+.SH PORTABILITY
+These functions are described in the XSI Curses standard, Issue 4.
+.PP
+Very old systems (before standardization) provide a different function
+with the same name:
+.bP
+The \fBwinch\fP function was part of the original BSD curses library,
+which stored a 7-bit character combined with the \fIstandout\fP attribute.
+.IP
+In BSD curses, \fBwinch\fP returned only the character (as an integer)
+with the \fIstandout\fP attribute removed.
+.bP
+System V curses added support for several video attributes which
+could be combined with characters in the window.
+.IP
+Reflecting this improvement, the function was altered to return the
+character combined with all video attributes in a \fBchtype\fP value.
+.PP
+X/Open Curses does not specify
+the size and layout of attributes, color and character values in
+\fBchtype\fP; it is implementation-dependent.
+This implementation uses 8 bits for character values.
+An application using more bits, e.g., a Unicode value,
+should use the wide-character equivalents to these functions.
+.SH SEE ALSO
