- should contain a gnutls_x509_crq_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.

DESCRIPTIONThis function will return the alternative names, contained in the given certificate. It is the same as gnutls_x509_crq_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).
RETURNSthe 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 request does not have an Alternative name with the specified sequence number then GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE is returned.
