Function Documentation

MqReadDbg_RT()

void MqReadDbg_RT	(	MK_RT	mkrt,
		MQ_CTX const	ctx )

MqReadGetHandShake()

enum MqHandShakeE MqReadGetHandShake

(

MQ_CTX const

ctx

)

return the HandShake identifer …

Parameters

[in]

ctx

the MqContextS instance to work on

Returns

MqHandShakeE

MqReadGetNextType()

enum MkTypeE 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

MqReadGetNumItems()

MK_NUM 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

MqReadGetTransType()

enum MqTransTypeE MqReadGetTransType

(

MQ_CTX const

ctx

)

return the TransactionType identifer …

Parameters

[in]

ctx

the MqContextS instance to work on

Returns

MqTransTypeE

MqReadItemExists()

bool 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, MK_YES or MK_NO

MqReadUndo_RT()

enum MkErrorE MqReadUndo_RT	(	MK_RT	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

Returns

The MkErrorE status from the DEFAULT MkErrorC in MkRuntimeS::error_mk
