SPFILENOTIFY_STARTREGISTRATION message
When using the RegisterDlls INF directive to self-register DLLs, callers of SetupInstallFromInfSection may receive notifications on each file as it is registered or unregistered. To send a SPFILENOTIFY_STARTREGISTRATION notification to the callback routine once before registering a file, include SPINST_REGISTERCALLBACKAWARE plus SPINST_REGSVR in the Flags parameter of SetupInstallFromInfSection. To send notification of unregistration, include SPINST_REGISTERCALLBACKAWARE plus SPINST_UNREGSVR in the Flags parameter.
The callback routine specified by the MsgHandler parameter of SetupInstallFromInfSection must be the type PSP_FILE_CALLBACK. Set the Context parameter to the same Context specified in SetupInstallFromInfSection. Set the Notification parameter to SPFILENOTIFY_STARTREGISTRATION.
