A pointer to a ULONG
containing the number of EAs.
Input
Contains the number of EAs for which information
is requested. A value of -1 requests that information be returned for as
many EAs whose information fits in pvBuf.
Output
Contains the actual number of EAs for which information
is returned. When this value is greater than 1, enumerated information is
returned in a series of DENA2 data
structures. Each data structure is aligned on a doubleword boundary. The
first field of the data structure (oNextEntryOffset) contains the
number of bytes to the beginning of the next data structure. A value of
zero for oNextEntryOffset indicates that this is the last data structure.
