+rrdflush \- Flush the values for a spcific RRD file from memory.

+\&\fBrrdtool\fR \fBflushcached\fR
+[\fB\-\-daemon\fR\ \fIaddress\fR]
+\&\fIfilename\fR [\fIfilename\fR ...]
+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+The \fBflushcached\fR function connects to rrdcached, the \s-1RRD\s0 caching daemon,
+and issues a \*(L"flush\*(R" command for the given files. The daemon will put the
+files to the head of the update queue so they are written \*(L"soon\*(R". The
+status will be returned only after the files' pending updates have been
+written to disk.
+.IP "\fIfilename\fR" 8
+.IX Item "filename"
+The name(s) of the \fB\s-1RRD\s0\fR file(s) that are to be written to disk.
+.IP "\fB\-\-daemon\fR \fIaddress\fR" 8
+.IX Item "--daemon address"
+Address of the rrdcached daemon. If not specified, the
+\&\s-1RRDCACHED_ADDRESS\s0 environment variable must be set (see below). For a
+list of accepted formats, see the \fB\-l\fR option in the rrdcached
+manual.

+The following environment variables may be used to change the behavior of

+.IP "\fB\s-1RRDCACHED_ADDRESS\s0\fR" 4
+.IX Item "RRDCACHED_ADDRESS"
+If this environment variable is set it will have the same effect as specifying
+the \f(CW\*(C`\-\-daemon\*(C'\fR option on the command line. If both are present, the command
+line argument takes precedence.
