SCTP_OPT_INFO(3) Library Functions Manual SCTP_OPT_INFO(3) NAME sctp_opt_info - get SCTP socket information LIBRARY Standard C Library (libc, -lc) SYNOPSIS #include <sys/types.h> #include <sys/socket.h> #include <netinet/sctp.h> int sctp_opt_info(int sd, sctp_assoc_t id, int opt, void *arg, socklen_t *size); DESCRIPTION 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 those who wish to write portable code amongst multiple operating systems this call should be used for the following SCTP socket options. SCTP_RTOINFO SCTP_ASSOCINFO SCTP_PRIMARY_ADDR SCTP_PEER_ADDR_PARAMS SCTP_DEFAULT_SEND_PARAM SCTP_MAX_SEG SCTP_AUTH_ACTIVE_KEY SCTP_DELAYED_SACK SCTP_MAX_BURST SCTP_CONTEXT SCTP_EVENT SCTP_DEFAULT_SNDINFO SCTP_DEFAULT_PRINFO SCTP_STATUS SCTP_GET_PEER_ADDR_INFO SCTP_PEER_AUTH_CHUNKS SCTP_LOCAL_AUTH_CHUNKS RETURN VALUES The call returns 0 on success and -1 upon error. ERRORS The sctp_opt_info() function can return the following errors: [EBADF] The argument s is not a valid descriptor. [EINVAL] The argument arg value was invalid.
