Method For Comparing Data Structures That Cross Address Space Boundaries
US Patent:
5774719, Jun 30, 1998
Filed:
Jan 8, 1993
Appl. No.:
8/002168
Inventors:

Abstract:
A method in accordance with the invention involves the normalization of a C language-type data structure received by a process in a distributed computing environment (DCE) to ensure that padding bits are consistently used. The method steps may advantageously be performed by a client process prior to and subsequent to a remote procedure call (RPC) to ensure that the padding bits are not undesirably changed as a result of the RPC. The method steps can also be performed by a server process to ensure that the structures it receives in RPCs are consistent in their use of padding bits. Normalization of the data structure permits a memcmp( ) or similar comparison function to be used to compare data structures without the risk that dissimilar padding bits will result in a false negative from the comparison.
