34/* Shared Folders Host Service.
35 *
36 * Shared Folders map a host file system to guest logical filesystem.
37 * A mapping represents 'host name'<->'guest name' translation and a root
38 * identifier to be used to access this mapping.
39 * Examples: "C:\WINNT"<->"F:", "C:\WINNT\System32"<->"/mnt/host/system32".
40 *
41 * Therefore, host name and guest name are strings interpreted
42 * only by host service and guest client respectively. Host name is
43 * passed to guest only for informational purpose. Guest may for example
44 * display the string or construct volume label out of the string.
45 *
46 * Root identifiers are unique for whole guest life,
47 * that is until next guest reset/fresh start.
48 * 32 bit value incremented for each new mapping is used.
49 *
50 * Mapping strings are taken from VM XML configuration on VM startup.
51 * The service DLL takes mappings during initialization. There is
52 * also API for changing mappings at runtime.
53 *
54 * Current mappings and root identifiers are saved when VM is saved.
55 *
56 * Guest may use any of these mappings. Full path information
57 * about an object on a mapping consists of the root identifier and
58 * a full path of object.
59 *
60 * Guest IFS connects to the service and calls SHFL_FN_QUERY_MAP
61 * function which returns current mappings. For guest convenience,
62 * removed mappings also returned with REMOVED flag and new mappings
63 * are marked with NEW flag.
64 *
65 * To access host file system guest just forwards file system calls
66 * to the service, and specifies full paths or handles for objects.
