Last updated Friday, 21 July 2017Gets diagnostic information about the last exception generated. Information about the last exception generated on the current thread is returned in a CCI_EXCEPTION_ST output structure. The user-defined extension can use this function to determine whether any recovery is required when a utility function returns an error code.
You can call this function when a utility function or user exit callback indicates that an exception has occurred, by setting returnCode to CCI_EXCEPTION.
You must call cciGetLastExceptionData() only when CCI_EXCEPTION is indicated; at other times, the function returns unpredictable results.
The traceText that is associated with the exception converts to a char* if the char* is US-ASCII. If the traceText is in another language, use cciGetLastExceptionDataW and its associated CCI_EXCEPTION_WIDE_ST structure, which stores the traceText as UTF-16.
If the exception has been raised by the broker, or by cciThrowExceptionW, the traceText element of the CCI_EXCEPTION_ST structure is an empty string.
void* cciGetLastExceptionData(
int* returnCode,
CCI_EXCEPTION_ST* exception_st);The value returned in the exception_st.messageNumber field, for exceptions resulting in a BIP cataloged exception message, contains the message level in the high order bytes and the BIP message number in the lower four bytes.
None. If an error occurs, the returnCode parameter indicates the reason for the error.
