Server-Class Send Operation Number
•
If the canceled call was to SERVERCLASS_DIALOG_BEGIN_ or
SERVERCLASS_DIALOG_SEND_, the dialog is aborted and the server receives a
Pathsend dialog abort system message, even if the server has already replied to the
server-class send operation.
•
If the SERVERCLASS_SEND_, SERVERCLASS_DIALOG_BEGIN_, or
SERVERCLASS_DIALOG_SEND_ operation was performed within a TMF
transaction, the transaction is automatically aborted.
On a call to CANCELREQ, you supply:
•
The server-class send operation number as the file-number parameter.
•
The tag identifying the specific operation to be canceled. (The tag is optional.)
If you use the tag parameter, the system cancels the oldest incomplete
SERVERCLASS_SEND_, SERVERCLASS_DIALOG_BEGIN_, or
SERVERCLASS_DIALOG_SEND_ call with that tag value. If you do not provide a
tag, the system cancels the oldest incomplete SERVERCLASS_SEND_,
SERVERCLASS_DIALOG_BEGIN_, or SERVERCLASS_DIALOG_SEND_ call.
On a call to CANCEL, you supply the server-class send operation number as the
file-number parameter.
Refer to the Guardian Procedure Calls Reference Manual for descriptions of the
CANCEL and CANCELREQ procedures.
A cancel operation can also occur if the requester abends while a server-class send
operation is in progress, whether or not the send operation was invoked with the nowait
option.
Calling FILEINFO
You can use the server-class send operation number returned by
SERVERCLASS_SEND_, SERVERCLASS_DIALOG_BEGIN_, or
SERVERCLASS_DIALOG_SEND_ as the file-number parameter in calls to FILEINFO
to get the return error associated with the last waited or nowait
SERVERCLASS_SEND_, SERVERCLASS_DIALOG_BEGIN_, or
SERVERCLASS_DIALOG_SEND_ call. FILEINFO returns the same error that the
server-class procedure call returned. See the error parameter in the procedure-call
syntax descriptions earlier in this section for details about the return errors.
