will be non zero if the extension is marked as critical
pointer to output integer indicating path length (may be NULL), non-negative values indicate a present pCPathLenConstraint 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 (2.5.29.19).
If the certificate is a CA a positive value will be returned, or zero if the certificate does not have CA flag set. A negative value 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.
