sctpsinfo_t Structure

The sctpsinfo_t structure contains informations about stable SCTP details from sctp_t.

typedef struct sctpsinfo {
        uintptr_t sctps_addr;           /* pointer to sctp_t */
        int sctps_num_raddrs;           /* number of remote addresses*/
        uintptr_t sctps_raddrs;         /* pointer to sctp_faddrs */
        int sctps_num_laddrs;
        uintptr_t sctps_laddrs;        /* pointer to sctp_saddrs */
        uint16_t sctps_lport;           /* local port */
        uint16_t sctps_rport;           /* remote port */
        string sctps_laddr;             /* local address, as a string */
        string sctps_raddr;             /* remote address, as a string */
        int32_t sctps_state;
} sctpsinfo_t;

It might seem redundant to supply the local and remote ports and addresses here and in the sctpinfo_t, but the sctp:::state-change probes do not have associated sctpinfo_t data. To map the state change to a specific port, we need the associated sctpinfo_t data.

The following table contains the members of scptsinfo_t structure:

Table 11-63 sctpsinfo_t Members

Member	Description
sctps_addr	Address of translated sctp_t *.
sctps_num_raddrs	Number of remote addresses.
sctps_raddrs	Pointer to first sctp_faddr_t *.
sctps_num_laddrs	Number of local addresses.
sctps_laddrs	Pointer to sctp_saddrs* address.
sctps_lport	Local port associated with the SCTP connection.
sctps_rport	Remote port associated with the SCTP connection.
sctps_laddr	Local address associated with the SCTP connection, as a string.
sctps_raddr	Remote address associated with the SCTP connection, as a string.
sctps_state	SCTP state. Inline definitions are provided for the various SCTP states such as SCTP_STATE_CLOSE and SCTP_STATE_IDLE. Use inline sctp_state_string[] to convert state to a string.
