@deftypefun {void} {gnutls_transport_set_int} (gnutls_session_t @var{session}, int @var{fd}) @var{session}: is a @code{gnutls_session_t} type. @var{fd}: is the socket descriptor for the connection. This function sets the first argument of the transport function, such as @code{send()} and @code{recv()} for the default callbacks using the system's socket API. This function is equivalent to calling @code{gnutls_transport_set_ptr()} with the descriptor, but requires no casts. @strong{Since:} 3.1.9 @end deftypefun
