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 FreeBSD a direct getsockopt() may be used, since FreeBSD has the ability to pass informa-
     tion into the operating system on a getsockopt() call.  Other operating systems may not have this ability.  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:

     [EINVAL]		The argument arg value was invalid.

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

     [EBADF]		The argument s is not a valid descriptor.

     [ENOTSOCK] 	The argument s is not a socket.

SEE ALSO

     getsockopt(2), sctp(4)

BUGS

     Because the structure used for arg of the SCTP_MAX_BURST socket option has changed in FreeBSD 9.0 and higher, using SCTP_MAX_BURST as opt is
     only supported in FreeBSD 9.0 and higher.

NAME

       sctp_optinfo - Get options on a SCTP socket.

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

       sctp_opt_info  is a wrapper library function that can be used to get SCTP level options on a socket.  sd is the socket descriptor for which
       the option is requested. For one-to-many style sockets, id specifies the association to query. For one-to-one style sockets, id is ignored.
       opt  specifes  the  SCTP  socket option to get.	arg is an option-specific structure buffer provided by the caller.  size is a value-result
       parameter, initially containing the size of the buffer pointed to by arg and modifed on return to indicate the actual  size  of	the  value
       returned.

RETURN VALUE

       On success, sctp_opt_info returns 0 and on failure -1 is returned with errno set to the appropriate error code.
