@deftypefun {int} {gnutls_x509_trust_list_add_crls} (gnutls_x509_trust_list_t @var{list}, const gnutls_x509_crl_t * @var{crl_list}, unsigned @var{crl_size}, unsigned int @var{flags}, unsigned int @var{verification_flags})
@var{list}: The list

@var{crl_list}: A list of CRLs

@var{crl_size}: The length of the CRL list

@var{flags}: flags from @code{gnutls_trust_list_flags_t} 

@var{verification_flags}: gnutls_certificate_verify_flags if flags specifies GNUTLS_TL_VERIFY_CRL

This function will add the given certificate revocation lists
to the trusted list. The CRLs in  @code{crl_list} must not be deinitialized
during the lifetime of  @code{list} .

This function must be called after @code{gnutls_x509_trust_list_add_cas()} 
to allow verifying the CRLs for validity. If the flag @code{GNUTLS_TL_NO_DUPLICATES} 
is given, then the final CRL list will not contain duplicate entries.

If the flag @code{GNUTLS_TL_NO_DUPLICATES}  is given, @code{gnutls_x509_trust_list_deinit()}  must be
called with parameter  @code{all} being 1.

If flag @code{GNUTLS_TL_VERIFY_CRL}  is given the CRLs will be verified before being added,
and if verification fails, they will be skipped.

@strong{Returns:} The number of added elements is returned; that includes
duplicate entries.

@strong{Since:} 3.0
