MQZEP - Add component entry point
This function is invoked by a service component, during initialization, to add an entry point to the entry point vector for that service component.
Syntax
- MQZEP (Hconfig, Function, EntryPoint, CompCode, Reason)
Parameters
The MQZEP call has the following parameters.
Hconfig (MQHCONFIG) - input
This handle represents the component which is being configured for this particular installable service. It must be the same as the one passed to the component configuration function by the queue manager on the component initialization call.
Function (MQLONG) - input
Function identifier.
Valid values for this are defined for each installable service.
If MQZEP is called more than once for the same function, the last call made provides the entry point which is used.
EntryPoint (PMQFUNC) - input
Function entry point.
This is the address of the entry point provided by the component to perform the function.
The value NULL is valid, and indicates that the function is not provided by this component. NULL is assumed for entry points which are not defined using MQZEP .
CompCode (MQLONG) - output
Completion code.
It is one of the following:
- MQCC_OK
- Successful completion.
- MQCC_FAILED
- Call failed.
Reason (MQLONG) - output
Reason code qualifying CompCode.
If CompCode is MQCC_OK:
- MQRC_NONE
- (0, X'000') No reason to report.
If CompCode is MQCC_FAILED:
- MQRC_FUNCTION_ERROR
- (2281, X'8E9') Function identifier not valid.
- MQRC_HCONFIG_ERROR
- (2280, X'8E8') Configuration handle not valid.
