gnutls_x509_crt_get_basic_constraints - API function
cert, unsigned int * critical, unsigned int *
ca, int * pathlen);
- gnutls_x509_crt_t cert
- should contain a gnutls_x509_crt_t type
- unsigned int * critical
- will be non-zero if the extension is marked as critical
- unsigned int * ca
- pointer to output integer indicating CA status, may be NULL, value is 1 if
the certificate CA flag is set, 0 otherwise.
- int * pathlen
- pointer to output integer indicating path length (may be NULL),
non-negative error codes indicate a present pathLenConstraint field and
the actual value, -1 indicate that the field is absent.
This function will read the certificate's basic constraints, and return the
certificates CA status. It reads the basicConstraints X.509 extension
If the certificate is a CA a positive value will be returned, or (0) if the
certificate does not have CA flag set. A negative error code may be returned
in case of errors. If the certificate does not contain the basicConstraints
extension GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.
