/// <summary>
/// Helper function to compare the data of a PLIST_DATA node against
/// a given blob and size.
/// This function basically behaves like memcmp after making sure the
/// size of the node's data value is equal to the size of cmpval (n),
/// making this a "full match" comparison.
/// </summary>
/// <param name="datanode">
/// node of type PLIST_DATA

/// <param name="cmpval">
/// data blob to compare against

/// <param name="n">
/// size of data blob passed in cmpval
/// </param>
/// <returns>
/// 0 if the node's data blob and cmpval are equal,
/// > 0 if the node's value is lexicographically greater than cmpval,
/// or

/// 0 if the node's value is lexicographically less than cmpval.
