This header is used by System Services. For more information, see:
vswriter.h contains the following programming interfaces:
CVssWriter The CVssWriter class is an abstract base class that defines the interface by which a writer synchronizes its state with VSS and other writers. |
CVssWriterEx The CVssWriterEx class is an abstract base class that defines the interface by which a writer synchronizes its state with VSS and other writers. |
CVssWriterEx2 The CVssWriterEx2 class is an abstract base class that defines the interface by which a writer synchronizes its state with VSS and other writers. |
IVssComponent The IVssComponent interface is a C++ (not COM) interface containing methods for examining and modifying information about components contained in a requester's Backup Components Document. |
IVssComponentEx Defines additional methods for examining and modifying information about components contained in a requester's Backup Components Document. |
IVssComponentEx2 Defines additional methods for reporting and retrieving component-level writer errors. |
IVssCreateExpressWriterMetadata The IVssCreateExpressWriterMetadata interface is a COM interface containing methods to construct the Writer Metadata Document for an express writer. |
IVssCreateWriterMetadata The IVssCreateWriterMetadata interface is a C++ (not COM) interface containing methods to construct the Writer Metadata Document in response to an Identify event. It is used only in the CVssWriter::OnIdentify method. |
IVssCreateWriterMetadataEx The IVssCreateWriterMetadataEx interface is a C++ (not COM) interface that defines a method to report any file sets that will be explicitly excluded when a shadow copy is created. |
IVssExpressWriter Defines methods to manage metadata for a VSS express writer. |
IVssWMDependency The IVssWMDependency is a C++ (not COM) interface returned by the IVssWMComponent interface and used by applications when backing up or restoring a component that has an explicit writer-component dependency on a component managed by another writer. |
IVssWMFiledesc The IVssWMFiledesc interface is a C++ (not COM) interface returned to a calling application by a number of query methods. It provides detailed information about a file or set of files (a file set). |
IVssWriterComponents Contains methods used to obtain and modify component information. |
CreateVssExpressWriter The CreateVssExpressWriter function (vswriter.h) creates an IVssExpressWriter interface object and returns a pointer to it. |
CreateVssExpressWriterInternal The CreateVssExpressWriterInternal function (vswriter.h) creates an IVssExpressWriter interface object and returns a pointer to it. |
CreateWriter This function is reserved for system use. (CreateWriter) |
CreateWriterEx This function is reserved for system use. (CreateWriterEx) |
VSS_ALTERNATE_WRITER_STATE Used to indicate whether a given writer has an associated alternate writer. |
VSS_COMPONENT_FLAGS Used by writers to indicate support for auto-recovery. |
VSS_COMPONENT_TYPE Specify the type of component being used with a shadow copy backup operation. |
VSS_FILE_RESTORE_STATUS Defines the set of statuses of a file restore operation. |
VSS_RESTORE_TARGET Used by a writer at restore time to indicate how all the files included in a selected component, and all the files in any component set it defines, are to be restored. |
VSS_RESTOREMETHOD_ENUM Used by a writer at backup time to specify through its Writer Metadata Document the default file restore method. |
VSS_SOURCE_TYPE Specifies the type of data that a writer manages. |
VSS_SUBSCRIBE_MASK Indicates the events that the writer is willing to receive. |
VSS_USAGE_TYPE Specifies how the host system uses the data managed by a writer involved in a VSS operation. |
VSS_WRITERRESTORE_ENUM Indicate to a requester the conditions under which it will handle events generated during a restore operation. |
