.SH DESCRIPTION
|
|
The \fBtouchwin\fR and \fBtouchline\fR routines throw away all
|
|
optimization information about which parts of the window have been
|
|
touched, by pretending that the entire window has been drawn on. This
|
|
is sometimes necessary when using overlapping windows, since a change
|
|
to one window affects the other window, but the records of which lines
|
|
have been changed in the other window do not reflect the change. The
|
|
routine \fBtouchline\fR only pretends that \fIcount\fR lines have been
|
|
changed, beginning with line \fIstart\fR.
|
|
|
|
The \fBuntouchwin\fR routine marks all lines in the window as unchanged since
|
|
the last call to \fBwrefresh\fR.
|
|
|
|
The \fBwtouchln\fR routine makes \fIn\fR lines in the window, starting
|
|
at line \fIy\fR, look as if they have (\fIchanged\fR\fB=1\fR) or have
|
|
not (\fIchanged\fR\fB=0\fR) been changed since the last call to
|
|
\fBwrefresh\fR.
|
|
|
|
The \fBis_linetouched\fR and \fBis_wintouched\fR routines return
|
|
\fBTRUE\fR if the specified line/window was modified since the last
|
|
call to \fBwrefresh\fR; otherwise they return \fBFALSE\fR. In
|
|
addition, \fBis_linetouched\fR returns \fBERR\fR if \fIline\fR is not
|
|
valid for the given window.
|
|
.SH RETURN VALUE
|
|
All routines return the integer \fBERR\fR upon failure and an integer value
|
|
other than \fBERR\fR upon successful completion, unless otherwise noted in the
|
|
preceding routine descriptions.
|
|
.SH NOTES
|
|
Note that all routines except \fBwtouchln\fR may be macros.
