values of predefined video attribute constants that can be usefully OR'ed
into characters.
.SS Echoing characters
-.PP
The \fBechochar\fP and \fBwechochar\fP routines are equivalent to a call to
\fBaddch\fP followed by a call to \fBrefresh\fP(3X), or a call to \fBwaddch\fP
followed by a call to \fBwrefresh\fP.
All these functions are described in the XSI Curses standard, Issue 4.
The defaults specified for forms-drawing characters apply in the POSIX locale.
.SS ACS Symbols
-.LP
X/Open Curses states that the \fBACS_\fP definitions are \fBchar\fP constants.
For the wide-character implementation (see \fBcurs_add_wch\fP),
there are analogous \fBWACS_\fP definitions which are \fBcchar_t\fP constants.
.bP
call \fBwadd_wch\fP for characters which cannot be handled by \fBwaddch\fP.
.SS TABSIZE
-.LP
The \fBTABSIZE\fP variable is implemented in SVr4 and other versions of curses,
but is not part of X/Open curses
(see \fBcurs_variables\fP(3X) for more details).
