Module Name:
routing\ip\rtrmgr\access.c
Abstract:
All the "access" functions take similar arguments:
dwQueryType This is the type of the query and can be
ACCESS_GET
ACCESS_GET_FIRST,
ACCESS_GET_NEXT,
ACCESS_SET,
ACCESS_CREATE_ENTRY,
ACCESS_DELETE_ENTRY
dwInEntrySize Size of the input buffer. The information
in the input buffer is dependent on the query type and
the information being queried. The input buffer stores
the QueryInfo which is a variable sized structure taking
an array of instance ids. The dwInEntrySize is used to
figure out how many instance ids are in the array (since
and explicit count is not given)
pInEntry Pointer to the input buffer. This is a MIB_OPAQUE_QUERY
structure which contains an integer (dwType) which
indicates the object being queried (which is not used
since the demuxing based on that has already been done)
and a variable length array of integer instance ids
The instance id must be completely specified in case of
ACCESS_GET,
ACCESS_SET,
ACCESS_CREATE_ENTRY,
ACCESS_DELETE_ENTRY
but for the rest only the first 'n' components of
the instance id may be specified.
pOutEntrySize Pointer to the size of the output buffer. If this is 0
the caller is querying us for the size of buffer needed
If the supplied buffer size is too small, we set this
to the minimum required size and return
ERROR_INSUFFICIENT_BUFFER;
pOutEntry The output buffer which is a MIB_OPAQUE_INFO structure.
The function fills in the dwTyoe to indicate the object
being returned. That type is used to cast the opaque
variable sized buffer following the type
pbCache Pointer to BOOL which is set to TRUE if the corresponding
cache was updated. This is not used currently, but may
be used later for optimizations
