wrapper for MqContextHandleResolve with error-handline

Parameters

[in]

netHdl

The handle previously returned by MkObjectHandleGet.

Returns

Return an valid libmqmsgque::MQ_CTX or MK_NULL with an error set.

• If netHdl is MK_NULL than MK_NULL is returned and the upper-code decide how to deal with it.
• MqContextHandleResolve return an valid libmqmsgque::MQ_CTX or MK_NULL if the netHdl is invalid or the underlying object has already been deleted.
  • If a MK_NULL is returned than an error-message is created and a jump to the label error is done.
  • If a libmqmsgque::MQ_CTX is returned than the netHdl is valid.

Function Documentation

MqContextGetNull()

MQ_CTX libmqmsgque::MqContextGetNull ( void )

inline

Null-Slot - return a MqContextC typed NULL instance …

Definition at line 4226 of file LibMqMsgque_mq.h.

                                             {
    return (MQ_CTX)MK_NULL;
  }

Here is the caller graph for this function:

MqContextHandleGet_RT()

MK_HDL libmqmsgque::MqContextHandleGet_RT ( MK_RT const mkrt, MQ_CTX const ctx )

inline

Handle-Get-Slot - returns a export-hdl to the MqContextC useable for external storage

The export-hdl is a reference to an instance that can be stored in software and converted back into an instance using the MqContextHandleResolve.

The export-hdl is only valid until the Programming-Language-Micro-Kernel (PLMK) ends.

example: The export-hdl is used in rpc to identify an object across the network.

Parameters

[in]	mkrt	the MkRuntimeS instance to work on - the runtime argument, used by MK_RT_CALL (C-only)
[in]	ctx	the MqContextS instance to work on

Returns

the required export-hdl

MqContextHandleResolve_RT()

MQ_CTX libmqmsgque::MqContextHandleResolve_RT ( MK_RT const mkrt, MK_HDL const netHdl )

inline

Handle-Resolve-Slot - return a MqContextC from netHdl or MK_NULL if invalid…

The MqContextHandleResolve undo the MqContextHandleGet and is intended to export a unique identifer into external code not belonging to the Programming-Language-Micro-Kernel (PLMK).

Parameters

[in]	mkrt	the MkRuntimeS instance to work on - the runtime argument, used by MK_RT_CALL (C-only)
[in]	netHdl	handle former exported with MqContextHandleGet

Returns

the required handle or MK_NULL if netHdl is invalid

MqContextInstances_RT()

MQ_CTX libmqmsgque::MqContextInstances_RT ( MK_RT_PARSER_ONLY )

The head-instance is the last instance created.
