Specifies the number of fonts specified within the .uff file and identified by DATA_HEADER structures. This is also the number of UFF_FONTDIRECTORY structures within the .uff file.

nGlyphSets

Specifies the number of glyph sets specified within the .uff file and identified by DATA_HEADER structures. Some fonts might share a glyph set.

nVarData

Specifies the number of variable data sections specified within the .uff file and identified by DATA_HEADER structures.

offFontDir

Specifies the offset, in bytes, from the beginning of the .uff file to the beginning of the first UFF_FONTDIRECTORY structure.

dwFlags

Is a set of bit flags, as specified in the following table.

Flag Definition
