+ The f\bfl\blu\bus\bsh\bhc\bca\bac\bch\bhe\bed\bd function connects to rrdcached, the RRD caching daemon,
+ and issues a "flush" command for the given files. The daemon will put
+ the files to the head of the update queue so they are written "soon".
+ The status will be returned only after the files' pending updates have
+ been written to disk.
+
+ _\bf_\bi_\bl_\be_\bn_\ba_\bm_\be
+ The name(s) of the R\bRR\bRD\bD file(s) that are to be written to disk.
+
+ -\b--\b-d\bda\bae\bem\bmo\bon\bn _\ba_\bd_\bd_\br_\be_\bs_\bs
+ Address of the rrdcached daemon. If not specified, the RRD-
+ CACHED_ADDRESS environment variable must be set (see below).
+ For a list of accepted formats, see the -\b-l\bl option in the rrd-
+ cached manual.

+ The following environment variables may be used to change the behavior
+ of "rrdtool flushcached":
+
+ R\bRR\bRD\bDC\bCA\bAC\bCH\bHE\bED\bD_\b_A\bAD\bDD\bDR\bRE\bES\bSS\bS
+ If this environment variable is set it will have the same effect as
+ specifying the "--daemon" option on the command line. If both are
+ present, the command line argument takes precedence.
