gnutls_x509_crt_get_subject_alt_name2 - API function
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);
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)
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
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.
