COMMON COMMUNICATION ERRORS

GeoCOM is based on calling functions remotely. Because of the additional
communication layer the set of return codes increases with return codes based on
communication errors. Since all of these codes may be returned by any RPC we
will explain them here and omit them in the descriptions of the RPC's. See also
20-Appendix
Return Codes.
Return Code
RC_OK
RC_COM_CANT_ENCODE
RC_COM_CANT_DECODE
RC_COM_CANT_SEND
RC_COM_CANT_RECV

Fundamentals of Programming GeoCOM
Val Description
0 Successful termination, implies also no
communication error.
3073 Can't encode arguments in client. Returned
by the client to the calling application
directly, i.e. without anything being sent to
the transport layer and beyond.
3074 Can't decode results in client. Once an RPC
has been sent to the server and a reply has
been sent back, this return code states that the
encoded reply could not be decoded in the
client. This is usually the result of using
different versions of GeoCOM on client and
server.
3075 Failure in sending calls. If the resources at the
transmitting port have been allocated
previously, i.e. GeoCOM does not have
exclusive rights to the port, or if the
exception or similar routine has experienced a
failure, this error code is returned.
3076 Failure in receiving result. A failure has
occurred during reception of a packet at the
data link layer. This could be due to incorrect
parameter settings or noise on the line, etc..
