SCTP_OPT_INFO(3)        NetBSD 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 get-
     ting specific getsockopt() data where an association identification needs
     to be passed into the operating system.  For those who wish to write por-
     table 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.

     [ENOTSOCK]         The argument s is not a socket.

     [EOPNOTSUPP]       The argument opt was not one of the above listed SCTP
                        socket options.
