Function Documentation

MqContextErrorCopy_RT()

MQ_EXTERN enum MkErrorE libmqmsgque::MqContextErrorCopy_RT	(	MK_RT const	mkrt,
		MQ_CTXN const	targetCtx,
		MQ_CTXN const	sourceCtx )

copy a MkErrorS from the sourceCtx to the targetCtx …

In ccmqmsgque the a MkRuntimeC is only one error-object per thread but this error-object has also addiitional attributes to identify the source of the error. In addition the ccmqmsgque has also an extended-error-object libmqmsgque::MqErrorS which also has error-specific-attributes. The MqContextErrorCopy is used to copy an error frome sourceCtx to targetCtx and keep the additional attributes in sync.

Note

• by default… every error set in a slave is also set in the master.
• by default… the error is only copied if sourceCtx and targetCtx are different.
• by default… the error is not copied if targetCtx libmqmsgque::MqConfigS::master of sourceCtx.
• by default… the copy only happen if sourceCtx has an error.
• on copy… the error of sourceCtx will be reset.

Parameters

[in]	mkrt	the MkRuntimeS instance to work on - the runtime argument, used by MK_RT_CALL (C-only)
	targetCtx	the MqContextC object and the target of the error
	sourceCtx	the MqContextC object and the source of the error
