The composer_flush function removes the cached composer or all cached composers from memory. The comp parameter specifies a handle for the composer. The handle should be the handle returned by the composer_sysid function. If comp is not specified, all cached composers are removed.

Once a composer CCF file is parsed, the results are stored in memory. Composers can be written so that they retain static information about a previous run. If this static information can interfere with the composer operation, you should flush the composer after each use.

This function returns a 0 if the composer was not cached. It returns a 1 if the composers were removed.
