NAME         top

       gnutls_record_get_direction - API function

SYNOPSIS         top

       #include <gnutls/gnutls.h>

       int gnutls_record_get_direction(gnutls_session_t session);

ARGUMENTS         top

       gnutls_session_t session
                   is a gnutls_session_t type.

DESCRIPTION         top

       This function is useful to determine whether a GnuTLS function
       was interrupted while sending or receiving, so that select() or
       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.
       gnutls_handshake(), was interrupted and returned
       GNUTLS_E_INTERRUPTED or GNUTLS_E_AGAIN. After such an interrupt
       applications may call select() or poll() before restoring the
       interrupted GnuTLS function.

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

RETURNS         top

       0 if interrupted while trying to read data, or 1 while trying to
       write data.
