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.
