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. +.SH SEE ALSO +\fBncurses\fR(3X), \fBcurs_refresh\fR(3X). +.\"# +.\"# The following sets edit modes for GNU EMACS +.\"# Local Variables: +.\"# mode:nroff +.\"# fill-column:79 +.\"# End: |
