callback as service

MqContextC - the callback-function is used as a service-handle or as a event-handle …

A service is using a callback to act on an incoming service-request. The callback is linked to a MqContextC_ServiceApi_Identifer with MqServiceCreate or is used as argument to the MqSendEND_AND_CALLBACK function.

service callbacks are:

• MqServiceCreate, SendEND_AND_CALLBACK, SendEND_AND_SUB, SendEND_AND_TRANSACTION

Attention

The callback return an MkErrorE and to work propper the servive allways have to return the runtime-error-code-attribute attribute and not only MK_ERROR (MkErrorE.ERROR) or MK_OK (MkErrorE.OK).

A Proper return can be done using the following code:

1. MkRuntimeS::error_mk->MkErrorS::code (c: (*mkrt).error_mk.code)
2. MkRuntimeGetErrorCode (c: MkRuntimeGetErrorCode(mkrt))
3. MkErrorDEFAULT and MkErrorGetCode (c: MkErrorGetCode(MkErrorDEFAULT()))
