NAME

       gnutls_record_get_direction - API function

SYNOPSIS

       #include <gnutls/gnutls.h>

       int gnutls_record_get_direction(gnutls_session_t session);

ARGUMENTS

       gnutls_session_t session
                   is a gnutls_session_t type.

DESCRIPTION

       This  function  provides  information  about the internals of the record protocol and is only useful if a
       prior gnutls function call (e.g.  gnutls_handshake()) was interrupted for some  reason,  that  is,  if  a
       function  returned  GNUTLS_E_INTERRUPTED  or  GNUTLS_E_AGAIN.   In  such  a  case, you might want to call
       select() or poll() before calling the interrupted gnutls function again.  To  tell  you  whether  a  file
       descriptor  should  be selected for either reading or writing, gnutls_record_get_direction() returns 0 if
       the interrupted function was trying to read data, and 1 if it was trying to write data.

       This function's output is unreliable if you are using the
        session in different threads, for sending and receiving.

RETURNS

       0 if trying to read data, 1 if trying to write data.
