2.5.1 Fib

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.

Value of nFib	cbRgFcLcb
0x00C1	0x005D
0x00D9	0x006C
0x0101	0x0088
0x010C	0x00A4
0x0112	0x00B7

fibRgFcLcbBlob (variable): The FibRgFcLcb.

cswNew (2 bytes): An unsigned integer that specifies the count of 16-bit values corresponding to fibRgCswNew that follow. This MUST be one of the following values, depending on the value of nFib.

Value of nFib	cswNew
0x00C1	0
0x00D9	0x0002
0x0101	0x0002
0x010C	0x0002
0x0112	0x0005

fibRgCswNew (variable): If cswNew is nonzero, this is fibRgCswNew. Otherwise, it is not present in the file.
