The WIM_PROVIDER_EXTERNAL_INFO structure holds the identifier and status information for the Windows Image File (WIM) external backing provider.
VersionThe WIM provider version. Set to WIM_PROVIDER_CURRENT_VERSION.
FlagsThe status flags for the WIM provider. Set to 0 when active. Otherwise Flags is set to one of the following values.
| Value | Meaning |
|---|---|
| WIM_PROVIDER_EXTERNAL_FLAG_NOT_ACTIVE | The WIM provider is not active, which can occur when the WIM file is not found. In this case, the WIM file will not be recovered. |
| WIM_PROVIDER_EXTERNAL_FLAG_SUSPENDED | Indicates that the provider is dismounted. Recovery will be attempted. |
DataSourceIdAn identifier value for the WIM file data source.
ResourceHashAn identifier for the object contained within the WIM. Conventionally a hash of the contents of a file, stored within the WIM.
The backing source for a file is set with a FSCTL_SET_EXTERNAL_BACKING control code request. The WIM file backing the file specified in the request is set in the DataSourceId member of WIM_PROVIDER_EXTERNAL_INFO.
The Flags and ResourceHash members are valid when the provider info is returned from a FSCTL_GET_EXTERNAL_BACKING request.
