After initialization, Client-Library applications must handle two types of error and informational messages:
Client-Library messages, or client messages, are generated by Client-Library. They range in severity from informational messages to fatal errors.
Server messages are generated by the server. They range in severity from informational messages to fatal errors.
Adaptive Server stores the text of its messages in the sysmessages system table. See the Adaptive Server Enterprise Reference Manual for a description of this table.
See the Open Server Server-Library/C Reference Manual for a list of Open Server messages.
Do not confuse Client-Library and server messages with
a result set of type CS_MSG_RESULT.
Client-Library and server messages are the means through which Client-Library
and the server communicate error and informational conditions to
an application. An application accesses Client-Library and server
messages either through message callback routines or inline, using ct_diag.
A message result set, on the other hand, is one of several types
of result sets that a server may return to an application. An application processes
a result set of type CS_MSG_RESULT by
calling ct_res_info to
get the message’s ID.
