A Monitor Client Library application installs an error handler when it creates a connection (smc_connect_alloc, described on §). This error handler is called whenever an error occurs for that connection.
Most Monitor Client Library functions return one of the following values:
Return value |
Description |
|---|---|
SMC_RET_SUCCESS |
The function completed successfully. |
SMC_RET_FAILURE |
The function failed. More detailed information is available from the error handler. |
SMC_RET_INVALID_CONNECT |
The function did not execute because it was requested against an erroneous connection. The error handler is not invoked because error handlers are available only for valid connections. |
Other return values are listed with the functions that return them.
The error callback function is not triggered under certain
error conditions regarding data item specification in smc_create_view and smc_create_alarm. To
capture these error conditions, check the return code for these
functions.
