@deftypefun {int} {gnutls_x509_name_constraints_add_permitted} (gnutls_x509_name_constraints_t @var{nc}, gnutls_x509_subject_alt_name_t @var{type}, const gnutls_datum_t * @var{name})
@var{nc}: The nameconstraints

@var{type}: The type of the constraints

@var{name}: The data of the constraints

This function will add a name constraint to the list of permitted
constraints. The constraints  @code{type} can be any of the following types:
@code{GNUTLS_SAN_DNSNAME} , @code{GNUTLS_SAN_RFC822NAME} , @code{GNUTLS_SAN_DN} ,
@code{GNUTLS_SAN_URI} , @code{GNUTLS_SAN_IPADDRESS} . For the latter, an IP address
in network byte order is expected, followed by its network mask.

@strong{Returns:} On success, @code{GNUTLS_E_SUCCESS}  (0) is returned, otherwise a negative error value.

@strong{Since:} 3.3.0
