.SH DESCRIPTION
.sp
.LP
Whether a terminal returns 7 or 8 significant bits initially depends on the
control mode of the terminal driver.  The \fBmeta()\fR function forces the
number of bits to be returned by  \fBgetch\fR(3XCURSES) to be 7 (if \fIbf\fR is
\fBFALSE\fR) or 8 (if \fIbf\fR is  \fBTRUE\fR).
.sp
.LP
If the program handling the data can only pass 7-bit characters or strips the
8th bit, 8 bits cannot be handled.
.sp
.LP
If the \fBterminfo\fR capabilities \fBsmm\fR (meta_on) and \fBrmm\fR (meta_off)
are defined for the terminal, \fBsmm\fR is sent to the terminal  when
\fBmeta(\fR\fIwin\fR\fB, TRUE)\fR is called, and \fBrmm\fR is sent when
\fBmeta(\fR\fIwin\fR\fB, FALSE)\fR is called.
.sp
.LP
This function is useful when extending the non-text command set in applications
where the META key is used.
.SH RETURN VALUES
.sp
.LP
On success, the \fBmeta()\fR function returns \fBOK\fR. Otherwise, it returns
\fBERR\fR.
.SH ERRORS
.sp
.LP
None.
