NAME

       gnutls_x509_crt_get_subject_alt_name2 - API function

SYNOPSIS

       #include <gnutls/x509.h>

       int gnutls_x509_crt_get_subject_alt_name2(gnutls_x509_crt_t cert, unsigned int seq, void *
       san, size_t * san_size, unsigned int * san_type, unsigned int * critical);

ARGUMENTS

       gnutls_x509_crt_t cert
                   should contain a gnutls_x509_crt_t type

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

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

       size_t * san_size
                   holds the size of ret.

       unsigned int * san_type
                   holds     the     type     of     the     alternative     name     (one     of
                   gnutls_x509_subject_alt_name_t).

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

DESCRIPTION

       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  san_type even if the function fails for  some  reason
       (i.e.  the buffer provided is not enough).

RETURNS

       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   san_size
       is  not  large  enough to hold the value.  In that case  san_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.
