25 This function will return an intermediate type containing the name con‐
26 straints of the provided NameConstraints extension. That can be used in
27 combination with gnutls_x509_name_constraints_check() to verify whether
28 a server's name is in accordance with the constraints.
29
30 When the flags is set to GNUTLS_NAME_CONSTRAINTS_FLAG_APPEND, then if
31 the nc type is empty this function will behave identically as if the
32 flag was not set. Otherwise if there are elements in the nc structure
33 then the constraints will be merged with the existing constraints fol‐
34 lowing RFC5280 p6.1.4 (excluded constraints will be appended, permitted
35 will be intersected).
36
37 Note that nc must be initialized prior to calling this function.
38
40 On success, GNUTLS_E_SUCCESS [22m(0) is returned, GNUTLS_E_RE‐
41 QUESTED_DATA_NOT_AVAILABLE if the extension is not present, otherwise a
42 negative error value.
