NAMEgnutls_x509_crt_get_basic_constraints - API function
- gnutls_x509_crt_t cert
- should contain a gnutls_x509_crt_t structure
- unsigned int * critical
- will be non-zero if the extension is marked as critical

- 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.
DESCRIPTIONThis function will read the certificate's basic constraints, and return the certificates CA status. It reads the basicConstraints X.509 extension (22.214.171.124).
RETURNSIf 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.
