+.SH NAME
+\fBaddch\fR, \fBwaddch\fR, \fBmvaddch\fR, \fBmvwaddch\fR,
+\fBechochar\fR, \fBwechochar\fR - add a character (with attributes) to a
+\fBcurses\fR window, then advance the cursor
+.SH SYNOPSIS
+\fB#include <curses.h>\fR
+
+\fBint addch(chtype ch);\fR
+.br
+\fBint waddch(WINDOW *win, chtype ch);\fR
+.br
+\fBint mvaddch(int y, int x, chtype ch);\fR
+.br
+\fBint mvwaddch(WINDOW *win, int y, int x, chtype ch);\fR
+.br
+\fBint echochar(chtype ch);\fR
+.br
+\fBint wechochar(WINDOW *win, chtype ch);\fR
+.br
+.SH DESCRIPTION
+The \fBaddch\fR, \fBwaddch\fR, \fBmvaddch\fR and \fBmvwaddch\fR routines put
+the character \fIch\fR into the given window at its current window position,
+which is then advanced.  They are analogous to \fBputchar\fR in \fBstdio\fR(3).
+If the advance is at the right margin, the cursor automatically wraps to the
+beginning of the next line.  At the bottom of the current scrolling region, if
+\fBscrollok\fR is enabled, the scrolling region is scrolled up one line.
+
+If \fIch\fR is a tab, newline, or backspace, the cursor is moved appropriately
+within the window.  Backspace moves the cursor one character left; at the left
+edge of a window it does nothing.  Newline does a \fBclrtoeol\fR, then moves
+the cursor to the window left margin on the next line, scrolling the window if
+on the last line).  Tabs are considered to be at every eighth column.
+
+If \fIch\fR is any control character other than tab, newline, or backspace, it
+is drawn in \fB^\fR\fIX\fR notation.  Calling \fBwinch\fR after adding a
+control character does not return the character itself, but instead returns
+the ^-representation of the control character.
+
+Video attributes can be combined with a character argument passed to
+\fBaddch\fR or related functions by logical-ORing them into the character.
+(Thus, text, including attributes, can be copied from one place to another
+using \fBinch\fR and \fBaddch\fR.).  See the \fBcurs_attr\fR(3X) page for
+values of predefined video attribute constants that can be usefully OR'ed
+into characters.
+
+The \fBechochar\fR and \fBwechochar\fR routines are equivalent to a call to
+\fBaddch\fR followed by a call to \fBrefresh\fR, or a call to \fBwaddch\fR
+followed by a call to \fBwrefresh\fR.  The knowledge that only a single
+character is being output is used and, for non-control characters, a
+considerable performance gain may be seen by using these routines instead of
+their equivalents.
+.SS Line Graphics
+The following variables may be used to add line drawing characters to the
+screen with routines of the \fBaddch\fR family.  The default character listed
+below is used if the \fBacsc\fR capability doesn't define a terminal-specific
+replacement for it (but see the EXTENSIONS section below).  The names are
+taken from VT100 nomenclature.

+.SH RETURN VALUE
+All routines return the integer \fBERR\fR upon failure and \fBOK\fR on success
+(the SVr4 manuals specify only "an integer value other than \fBERR\fR") upon
+successful completion, unless otherwise noted in the preceding routine
+descriptions.
+.SH NOTES
+Note that \fBaddch\fR, \fBmvaddch\fR, \fBmvwaddch\fR, and
+\fBechochar\fR may be macros.
+.SH PORTABILITY
+All these functions are described in the XSI Curses standard, Issue 4.
+The defaults specified for forms-drawing characters apply in the POSIX locale.

+Some ACS symbols
+(ACS_S3,
+ACS_S7,
+ACS_LEQUAL,
+ACS_GEQUAL,
+ACS_PI,
+ACS_NEQUAL,
+ACS_STERLING)
+were not documented in
+any publicly released System V.  However, many publicly available terminfos
+include \fBacsc\fR strings in which their key characters (pryz{|}) are
+embedded, and a second-hand list of their character descriptions has come
+to light.  The ACS-prefixed names for them were invented for \fBncurses\fR(3X).
