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 does not define a terminal-specific
replacement for it.
The names are taken from VT100 nomenclature.

+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 \fBaddch\fR, \fBmvaddch\fR, \fBmvwaddch\fR, and
\fBechochar\fR may be macros.
All these functions are described in the XSI Curses standard, Issue 4.
The defaults specified for forms-drawing characters apply in the POSIX locale.
.LP
+X/Open Curses states that the \fIACS_\fP definitions are \fBchar\fP constants.
+For the wide-character implementation (see \fBcurs_add_wch\fP),
+there are analogous \fIWACS_\fP definitions which are \fBcchar_t\fP constants.
