class SyncClientBuffered
Defined at line 114 of file ../../zircon/system/ulib/sysconfig-client/include/lib/sysconfig/sync-client.h
SynClientBuffered is a wrapper of SyncClient added with write-caching capability.
It buffers all the write to sysconfig partition to an internal buffer first.
The bufferred data is written to persistant storage by explicitly calling its Flush() method.
