Gets SCTP socket information.

int
sctp_opt_info(int s, sctp_assoc_t, int opt, void *arg, socklen_t *size);

Library

Standard C Library (libc, -lc)

Remarks

The sctp_opt_info() call provides a multi-os compatible method for getting specific getsockopt() data where an association identification needs to be passed into the operating system. For FreeBSD a direct getsockopt() may be used, since FreeBSD has the ability to pass information into the operating system on a getsockopt() call. ther operating systems may not have this ability. For those who wish to write portable code amongst multiple operating systems this call should be used for the following SCTP socket options:

SCTP_RTOINF SCTP_ASSOCINFO SCTP_PRIMARY_ADDR SCTP_SET_PEER_PRIMARY_ADDR SCTP_STATUS SCTP_GET_PEER_ADDR_INFO SCTP_AUTH_ACTIVE_KEY SCTP_PEER_AUTH_CHUNKS SCTP_LOCAL_AUTH_CHUNKS
