Purpose |
Inform the application that a particular session has failed unexpectedly. |
|
|
|
|
Notice |
For this event notice, the notice parameter of the AspenEvent() function receives a pointer to an ASPEN_SESSION_FAILURE_NOTICE structure.
This structure is dynamically allocated by Aspen and must be freed using the AspenFreeMemory() function after use. |
|
|
|
|
Structure |
typedef struct { int session; char errorTag[16]; char errorText[80]; |
|
|
|
|
Remarks |
The ASPEN_SessionFailureNotice event is reported if a session fails unexpectedly (i.e., is terminated) due to some external cause.
This event will not be reported until all other pending events (such as instrument updates) pertaining to the indicated session have been reported and the request cycles for all outstanding service requests on the session have been completed.
An ASPEN_CloseSession service request used to close a normal, open session will not trigger this event
A terminated or failed session need not be formally closed using the ASPEN_CloseSession service. |
