NAME         top

       sctp_optinfo - Get options on a SCTP socket.

SYNOPSIS         top

       #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         top

       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         top

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