The PROPID_M_XACT_STATUS_QUEUE_LEN property indicates the length (in Unicode characters) of the transaction status queue's format name buffer.
The PROPID_M_XACT_STATUS_QUEUE_LEN property is used only by the connector application when calling MQReceiveMessage. It is required whenever PROPID_M_XACT_STATUS_QUEUE is passed in MQReceiveMessage.
On input, PROPID_M_XACT_STATUS_QUEUE_LEN specifies the length of the format name buffer (in Unicode characters) allocated by the receiving application. The buffer should be large enough to hold the format name string including the null-terminating character.
On return, this property holds the length (in Unicode characters) of the PROPID_M_XACT_STATUS_QUEUE format name string including the null-terminating character.
