NAME

       gnutls_session_get_id - API function

SYNOPSIS

       #include <gnutls/gnutls.h>

       int gnutls_session_get_id(gnutls_session_t session, void * session_id, size_t * session_id_size);

ARGUMENTS

       gnutls_session_t session
                   is a gnutls_session_t type.

       void * session_id
                   is a pointer to space to hold the session id.

       size_t * session_id_size
                   initially should contain the maximum  session_id size and will be updated.

DESCRIPTION

       Returns  the  current  session ID. This can be used if you want to check if the next session you tried to
       resume was actually resumed.  That is because resumed  sessions  share  the  same  session  ID  with  the
       original session.

       The  session  ID  is  selected  by  the  server, that identify the current session.  In all supported TLS
       protocols, the session id is less than GNUTLS_MAX_SESSION_ID_SIZE.

RETURNS

       On success, GNUTLS_E_SUCCESS (0) is returned, otherwise an error code is returned.
