ARGUMENTS

gnutls_x509_crt_t cert

should contain a gnutls_x509_crt_t structure

unsigned int * 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 (0) if the certificate does not have CA flag set.
