NAME
gnutls_x509_crt_get_ca_status - API function

SYNOPSIS
#include <gnutls/x509.h>

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.
