# [NAME](#NAME)

gnutls\_x509\_trust\_list\_add\_crls - API function

# [SYNOPSIS](#SYNOPSIS)

**#include <gnutls/x509.h>**

**int gnutls\_x509\_trust\_list\_add\_crls(gnutls\_x509\_trust\_list\_t list, const gnutls\_x509\_crl\_t * crl\_list, unsigned crl\_size, unsigned int flags, unsigned int verification\_flags);**

# [ARGUMENTS](#ARGUMENTS)

[gnutls\_x509\_trust\_list\_t list](#gnutls_x509_trust_list_t)

The list

[const gnutls\_x509\_crl\_t * crl\_list](#const)

A list of CRLs

[unsigned crl\_size](#unsigned)

The length of the CRL list

[unsigned int flags](#unsigned~2)

flags from **gnutls\_trust\_list\_flags\_t**

[unsigned int verification\_flags](#unsigned~3)

gnutls\_certificate\_verify\_flags if flags specifies GNUTLS\_TL\_VERIFY\_CRL

# [DESCRIPTION](#DESCRIPTION)

This function will add the given certificate revocation lists to the trusted list. The CRLs in *crl\_list* must not be deinitialized during the lifetime of *list* .

This function must be called after **gnutls\_x509\_trust\_list\_add\_cas()** to allow verifying the CRLs for validity. If the flag **GNUTLS\_TL\_NO\_DUPLICATES** is given, then the final CRL list will not contain duplicate entries.

If the flag **GNUTLS\_TL\_NO\_DUPLICATES** is given, **gnutls\_x509\_trust\_list\_deinit()** must be called with parameter *all* being 1.

If flag **GNUTLS\_TL\_VERIFY\_CRL** is given the CRLs will be verified before being added, and if verification fails, they will be skipped.

# [RETURNS](#RETURNS)

The number of added elements is returned; that includes duplicate entries.
