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.

       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.
