Синопсис (Synopsis)

int gnutls_x509_ext_import_name_constraints(const gnutls_datum_t
* ext, gnutls_x509_name_constraints_t nc, unsigned int flags);
Аргументы (Arguments)

a DER encoded extension
gnutls_x509_name_constraints_t nc
The nameconstraints
unsigned int flags
zero or GNUTLS_NAME_CONSTRAINTS_FLAG_APPEND
Описание (Description)
This function will return an intermediate type containing the
name constraints of the provided NameConstraints extension. That
can be used in combination with
gnutls_x509_name_constraints_check() to verify whether a server's
name is in accordance with the constraints.
When the flags is set to GNUTLS_NAME_CONSTRAINTS_FLAG_APPEND,
then 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 structure then the constraints will be merged
with the existing constraints following RFC5280 p6.1.4 (excluded
constraints will be appended, permitted will be intersected).
Note that nc must be initialized prior to calling this function.
Возвращаемое значение (Return value)
On success, GNUTLS_E_SUCCESS (0) is returned,
GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE if the extension is not
present, otherwise a negative error value.
