       int gnutls_x509_crq_get_attribute_info(gnutls_x509_crq_t crq,
       unsigned indx, void * oid, size_t * sizeof_oid);

ARGUMENTS         top

       gnutls_x509_crq_t crq
                   should contain a gnutls_x509_crq_t type

       void * oid  a pointer to a structure to hold the OID

       size_t * sizeof_oid
                   initially holds the maximum size of  oid , on return
                   holds actual size of  oid .
