FILE_POSITION_INFORMATION

typedef struct FILE_POSITION_INFORMATION {
    LARGE_INTEGER CurrentByteOffset;
} FILE_POSITION_INFORMATION, *PFILE_POSITION_INFORMATION;

Members

CurrentByteOffset

The byte offset of the current file pointer.

Comments

FILE_READ_DATA or FILE_WRITE_DATA access to the file is required to change this information about the file, and the file must be opened for synchronous I/O.

If the file was opened or created with the FILE_NO_INTERMEDIATE_BUFFERING option, the value of CurrentByteOffset must be an integral multiple of the sector size of the underlying device.
