Host name is * passed to guest only for informational purpose. Guest may for example * display the string or construct volume label out of the string. * * Root identifiers are unique for whole guest life, * that is until next guest reset/fresh start. * 32 bit value incremented for each new mapping is used. * * Mapping strings are taken from VM XML configuration on VM startup. * The service DLL takes mappings during initialization. There is * also API for changing mappings at runtime. * * Current mappings and root identifiers are saved when VM is saved. * * Guest may use any of these mappings. Full path information * about an object on a mapping consists of the root identifier and * a full path of object. * * Guest IFS connects to the service and calls SHFL_FN_QUERY_MAP * function which returns current mappings. For guest convenience, * removed mappings also returned with REMOVED flag and new mappings * are marked with NEW flag. * * To access host file system guest just forwards file system calls * to the service, and specifies full paths or handles for objects. * * */ static DECLCALLBACK(int) svcUnload (void *) { int rc = VINF_SUCCESS; Log(("svcUnload\n")); vbsfFreeHandleTable(); if (g_pHelpers) HGCMSvcHlpStamDeregister(g_pHelpers, "/HGCM/VBoxSharedFolders/*"); return rc; } static DECLCALLBACK(int) svcConnect (void *, uint32_t u32ClientID, void *pvClient, uint32_t fRequestor, bool fRestoring) { RT_NOREF(u32ClientID, fRequestor, fRestoring); SHFLCLIENTDATA *pClient = (SHFLCLIENTDATA *)pvClient; Log(("SharedFolders host service: connected, u32ClientID = %u\n", u32ClientID)); pClient->fHasMappingCounts = true; pClient->enmErrorStyle = SHFLERRORSTYLE_NATIVE; return VINF_SUCCESS; } static DECLCALLBACK(int) svcDisconnect (void *, uint32_t u32ClientID, void *pvClient) { RT_NOREF1(u32ClientID); int rc = VINF_SUCCESS; SHFLCLIENTDATA *pClient = (SHFLCLIENTDATA *)pvClient; Log(("SharedFolders host service: disconnected, u32ClientID = %u\n", u32ClientID)); vbsfDisconnect(pClient); return rc; } /** @note We only save as much state as required to access the shared folder again after restore. * All I/O requests pending at the time of saving will never be completed or result in errors. * (file handles no longer valid etc) * This works as designed at the moment.
