This function will return an intermediate type containing the name constraints
of the provided NameConstraints extension. That can be used in combination
to verify whether a server's
name is in accordance with the constraints.
When the flags
is set to GNUTLS_NAME_CONSTRAINTS_FLAG_APPEND
if the nc
type is empty this function will behave identically as if the
flag was not set. Otherwise if there are elements in the nc
then the constraints will be merged with the existing constraints following
RFC5280 p6.1.4 (excluded constraints will be appended, permitted will be
Note that nc
must be initialized prior to calling this function.
On success, GNUTLS_E_SUCCESS
(0) is returned,
if the extension is not present,
otherwise a negative error value.
