NAME         top

       gnutls_x509_crt_get_ca_status - API function

SYNOPSIS         top

       #include <gnutls/x509.h>

       int gnutls_x509_crt_get_ca_status(gnutls_x509_crt_t cert,
       unsigned int * critical);

ARGUMENTS         top

       gnutls_x509_crt_t cert
                   should contain a gnutls_x509_crt_t type

       unsigned int * critical
                   will be non-zero if the extension is marked as
                   critical

DESCRIPTION         top

       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.

       Use gnutls_x509_crt_get_basic_constraints() if you want to read
       the pathLenConstraint field too.

RETURNS         top

       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.
