gnutls_x509_crt_get_ca_status — API function
int gnutls_x509_crt_get_ca_status(gnutls_x509_crt_t cert, unsigned int * critical);

This function will return certificates CA status, by reading the basicConstraints X.509 extension (18.104.22.168). If the certificate is a CA a positive value will be returned, or (0) 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.
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.
