The ClfsSetLogFileInformation routine sets metadata and state information for a specified stream and its underlying physical log.
Syntax
CLFSUSER_API NTSTATUS ClfsSetLogFileInformation(
[in] PLOG_FILE_OBJECT plfoLog,
[in] CLFS_LOG_INFORMATION_CLASS eInformationClass,
[in] PVOID pinfoBuffer,
[in] ULONG cbBuffer
);
Parameters

| Value of eInformationClass | Type of buffer pointed to by pinfoBuffer |
|---|---|
| ClfsLogBasicInformation | |
| ClfsLogBasicInformationPhysical | |
| ClfsLogNameInformation | |
| ClfsLogPhysicalNameInformation | |
| ClfsLogStreamIdentifierInformation |
[in] cbBuffer
The size, in bytes, of the buffer pointed to by pinfoBuffer.
