       gnutls_x509_crt_get_subject_alt_name2 - API function


       #include <gnutls/x509.h>

       int gnutls_x509_crt_get_subject_alt_name2(gnutls_x509_crt_t cert, unsigned int seq, void *
       ret, size_t * ret_size, unsigned int * ret_type, unsigned int * critical);


       gnutls_x509_crt_t cert
                   should contain a gnutls_x509_crt_t structure

       unsigned int seq
                   specifies the sequence number of the alt name (0 for the first one, 1 for  the
                   second etc.)

       void * ret  is the place where the alternative name will be copied to

       size_t * ret_size
                   holds the size of ret.

       unsigned int * ret_type
                   holds     the     type     of     the     alternative     name     (one     of

       unsigned int * critical
                   will be non zero if the extension is marked as critical (may be null)


       This function will return the alternative names, contained in the given certificate. It is
       the same as gnutls_x509_crt_get_subject_alt_name() except for the fact that it will return
       the type of the alternative name in ret_type even if the function fails  for  some  reason
       (i.e.  the buffer provided is not enough).


       the    alternative    subject    name   type   on   success,   one   of   the   enumerated
       gnutls_x509_subject_alt_name_t.  It will return GNUTLS_E_SHORT_MEMORY_BUFFER  if  ret_size
       is  not  large  enough  to hold the value.  In that case ret_size will be updated with the
       required size.  If the certificate does not have an Alternative name  with  the  specified
       sequence number then GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE is returned.
