The ClfsReadRestartArea routine reads the restart record that was most recently written to a specified CLFS stream.
CLFSUSER_API NTSTATUS ClfsReadRestartArea( PVOID pvMarshalContext, PVOID *ppvRestartBuffer, PULONG pcbRestartBuffer, PCLFS_LSN plsn, PVOID *ppvReadContext );
A pointer to an opaque context that represents a marshalling area associated with a CLFS stream. The caller previously obtained this pointer by calling ClfsCreateMarshallingArea.
A pointer to a variable that receives a pointer to the data buffer of the restart record.
A pointer to a ULONG-typed variable that receives the size, in bytes, of the data buffer pointed to by pcbRestartBuffer. This is the length of the data buffer of the restart record.
A pointer to a CLFS_LSN structure that receives the LSN of the restart record that was read.
A pointer to a variable that receives a pointer to an opaque read context. The caller can pass this context to ClfsReadPreviousRestartArea or ClfsReadNextLogRecord. When the caller has finished using the read context, it must free the context by calling ClfsTerminateReadLog.
ClfsReadRestartArea returns STATUS_SUCCESS if it succeeds; otherwise, it returns one of the error codes defined in Ntstatus.h.
For an explanation of CLFS concepts and terminology, see Common Log File System.
Read contexts are not thread-safe. Clients are responsible for serializing access to read contexts.
