Function Documentation

MqReadDbg_RT()

MQ_EXTERN void libmqmsgque::MqReadDbg_RT	(	MK_RT const	mkrt,
		MQ_CTX const	ctx )

MqReadGetHandShake()

MQ_EXTERN enum MqHandShakeE libmqmsgque::MqReadGetHandShake

(

MQ_CTX const

ctx

)

return the HandShake identifer …

Parameters

[in]

ctx

the MqContextS instance to work on

Returns

libmqmsgque::MqHandShakeE

MqReadGetNextType()

MQ_EXTERN enum MkTypeE libmqmsgque::MqReadGetNextType

(

MQ_CTX const

ctx

)

get the type (MkTypeE) of the next Item in the read-data-buffer or "0" if not available

Parameters

[in]

ctx

the MqContextS instance to work on

Returns

the type

Here is the caller graph for this function:

MqReadGetNumItems()

MQ_EXTERN MK_NUM libmqmsgque::MqReadGetNumItems

(

MQ_CTX const

ctx

)

get the number of items left in the read-data-package …

Parameters

[in]

ctx

the MqContextS instance to work on

Returns

the number of items as integer

Here is the caller graph for this function:

MqReadGetTransType()

MQ_EXTERN enum MqTransTypeE libmqmsgque::MqReadGetTransType

(

MQ_CTX const

ctx

)

return the TransactionType identifer …

Parameters

[in]

ctx

the MqContextS instance to work on

Returns

libmqmsgque::MqTransTypeE

MqReadItemExists()

MQ_EXTERN bool libmqmsgque::MqReadItemExists

(

MQ_CTX const

ctx

)

check if an item exists in the read-data-package …

Parameters

[in]

ctx

the MqContextS instance to work on

Returns

boolean, true or false

Here is the caller graph for this function:

MqReadUndo_RT()

MQ_EXTERN enum MkErrorE libmqmsgque::MqReadUndo_RT	(	MK_RT const	mkrt,
		MQ_CTX const	ctx )

undo the last MqContextC READ API function call …

Put the internal position-pointer to the start of the last read body-item. The next read function call will extract the same item again. Only one undo level is supported.

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

Exceptions
