2.5.1 Fib

Office

The Fib structure contains information about the document and specifies the file pointers to various portions that make up the document.

The Fib is a variable length structure. With the exception of the base portion which is fixed in size, every section is preceded with a count field that specifies the size of the next section.

base (32 bytes): The FibBase.

csw (2 bytes): An unsigned integer that specifies the count of 16-bit values corresponding to fibRgW that follow. MUST be 0x000E.

fibRgW (28 bytes): The FibRgW97.

cslw (2 bytes): An unsigned integer that specifies the count of 32-bit values corresponding to fibRgLw that follow. MUST be 0x0016.

fibRgLw (88 bytes): The FibRgLw97.

cbRgFcLcb (2 bytes): An unsigned integer that specifies the count of 64-bit values corresponding to fibRgFcLcbBlob that follow. This MUST be one of the following values, depending on the value of nFib.
