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
