int gnutls_x509_crt_get_ca_status(gnutls_x509_crt_t cert, unsigned int * critical);
ARGUMENTS
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
DESCRIPTION
This function will return certificates CA status, by reading 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.
Use gnutls_x509_crt_get_basic_constraints() if you want to read the
pathLenConstraint field too.
RETURNS
A negative value may be returned in case of parsing error.
If the certificate does not contain the basicConstraints extension
GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.
