Routine Description:
This routine dumps the flags specified in Value according to the
description passing into FlagRecords. The formating is affected by
the flags field
Arguments:
Value - The values
FlagRecord - What each bit in the flags means
FlagRecordSize - How many flags there are
IndentLevel - The base indent level
Flags - How we will process the flags
Return Value:
ULONG - the number of characters printed. 0 if we printed nothing
