@deftypefun {int} {gnutls_record_get_direction} (gnutls_session_t @var{session})

@var{session}: is a @code{gnutls_session_t}  type.

This function is useful to determine whether a GnuTLS function was interrupted

while sending or receiving, so that @code{select()}  or @code{poll()}  may be called appropriately.

It provides information about the internals of the record

protocol and is only useful if a prior gnutls function call,

e.g.  @code{gnutls_handshake()} , was interrupted and returned

@code{GNUTLS_E_INTERRUPTED}  or @code{GNUTLS_E_AGAIN} . After such an interrupt

applications may call @code{select()}  or @code{poll()}  before restoring the

interrupted GnuTLS function.

This function's output is unreliable if you are using the same

 @code{session} in different threads for sending and receiving.

@strong{Returns:} 0 if interrupted while trying to read data, or 1 while trying to write data.
