       CA status

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.
