AP_MDS_MU_RECEIVED
first_message
Indicates whether this message is the first, or only,
message for this MDS_MU. The MDS_MU is normally
sent to the application as a single message (both
first_message and last_message are AP_YES).
However, if the MDS_MU is larger than the
max_rcv_size specified when the application issued
REGISTER_MS_APPLICATION, SNAplus2 segments
the MDS_MU and sends it to the application as
multiple messages. Possible values are:
AP_YES
First or only message for this
MDS_MU.
AP_NO
Second or subsequent message for
this MDS_MU.
last_message
Indicates whether this message is the last, or only,
message for this MDS_MU. The MDS_MU is normally
sent to the application as a single message (both
first_message and last_message are AP_YES).
However, if the MDS_MU is larger than the
max_rcv_size specified when the application issued
REGISTER_MS_APPLICATION, SNAplus2 segments
the MDS_MU and sends it to the application as
multiple messages. Possible values are:
AP_YES
Last or only message for this
MDS_MU.
AP_NO
First or subsequent message for a
segmented MDS_MU. At least one
more message follows.
