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.
