CMSG_OC_MSGNO is an encoded field consisting of 4 bytes:
Byte 1 (the high-order byte) represents the Client-Library layer that is reporting the error. This byte is normally only used by Sybase Technical Support.
Byte 2 represents the message’s origin and is used internally by Sybase.
Byte 3 denotes the severity of the error. Table 3-1 describes the possible values.
