@deftypefun {int} {gnutls_x509_ext_import_basic_constraints} (const gnutls_datum_t * @var{ext}, unsigned int * @var{ca}, int * @var{pathlen})

@var{ext}: the DER encoded extension data

@var{ca}: will be non zero if the CA status is true

@var{pathlen}: the path length constraint; will be set to -1 for no limit

This function will return the CA status and path length constraint

as written in the PKIX extension 2.5.29.19.

@strong{Returns:} On success, @code{GNUTLS_E_SUCCESS}  (0) is returned, otherwise a
