112	/** @page pg_shfl_svc Shared Folders Host Service
113	*
114	* Shared Folders map a host file system to guest logical filesystem.
115	* A mapping represents 'host name'<->'guest name' translation and a root
116	* identifier to be used to access this mapping.
117	* Examples: "C:\WINNT"<->"F:", "C:\WINNT\System32"<->"/mnt/host/system32".
118	*
119	* Therefore, host name and guest name are strings interpreted
120	* only by host service and guest client respectively. Host name is
121	* passed to guest only for informational purpose. Guest may for example
122	* display the string or construct volume label out of the string.
123	*
124	* Root identifiers are unique for whole guest life,
125	* that is until next guest reset/fresh start.
126	* 32 bit value incremented for each new mapping is used.
127	*
128	* Mapping strings are taken from VM XML configuration on VM startup.
129	* The service DLL takes mappings during initialization. There is
130	* also API for changing mappings at runtime.
131	*
132	* Current mappings and root identifiers are saved when VM is saved.
133	*
134	* Guest may use any of these mappings. Full path information
135	* about an object on a mapping consists of the root identifier and
136	* a full path of object.
137	*
138	* Guest IFS connects to the service and calls SHFL_FN_QUERY_MAP
139	* function which returns current mappings. For guest convenience,
140	* removed mappings also returned with REMOVED flag and new mappings
141	* are marked with NEW flag.
142	*
143	* To access host file system guest just forwards file system calls
144	* to the service, and specifies full paths or handles for objects.
