_CLS_WRITE_ENTRY structure

Description

The CLFS_WRITE_ENTRY structure holds the address and size of a buffer that contains one unit of data to be written to a Common Log File System (CLFS) stream.

Members

`Buffer`

A pointer to the buffer that holds the data.

`ByteLength`

The size, in bytes, of the buffer pointed to by Buffer.

Remarks

CLFS collects the buffers pointed to by several CLFS_WRITE_ENTRY structures into a single log record. The log record is then placed in a log I/O block along with other log records. Eventually the log I/O block is flushed to disk.
