Sysctl-like interface to read host information via a dot-separated
|
|
ASCII OID.
|
|
|
|
The information is copied into the buffer specified by Item. The
|
|
size of the buffer is given by the location specified by Size
|
|
before the call, and that location gives the amount of data copied
|
|
after a successfull call, and after a call that returns a truncated
|
|
value with an error return of RETURN_BUFFER_TOO_SMALL.
|
|
|
|
The size of the available data can be determined by passing a NULL
|
|
argument for Item. The size will be returned in the location pointed
|
|
to by Size.
|
|
|
|
@param[] Name - ASCII OID name
|
|
@param[] Data - return buffer pointer
|
|
@param[] Size - pointer to length
|
|
|

@return RETURN_SUCCESS Valid data/len returned.
