Abstract:
|
|
|
|
Data structures used for reading the common font installer file format.
|
|
Typically used by drivers during font counting and enumeration at
|
|
EnabldPDEV() time - at the time of writing! Subject to change as the
|
|
DDI/GDI change.
|
|
|
|
Environment:
|
|
|
|
Windows NT Unidrv driver
