The status field in the CS_SERVERMSG structure indicates whether the structure contains a whole message or a chunk of a message.
Table 2-6 lists status values that are related to sequenced messages:
Symbolic value |
To indicate |
---|---|
CS_FIRST_CHUNK |
The message text is the first chunk of the message. |
CS_LAST_CHUNK |
The message text is the last chunk of the message. |
An application sets both CS_FIRST_CHUNK and CS_LAST_CHUNK on if the message text in the structure is the entire message. An application sets neither CS_FIRST_CHUNK nor CS_LAST_CHUNK on if message text in the structure is a middle chunk. |
The textlen field in the CS_SERVERMSG structure always reflects the length of the current message chunk.
All other fields in the CS_SERVERMSG are repeated with each message chunk.
