# [NAME](#NAME)

gnutls\_x509\_crl\_verify - API function

# [SYNOPSIS](#SYNOPSIS)

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

**int gnutls\_x509\_crl\_verify(gnutls\_x509\_crl\_t crl, const gnutls\_x509\_crt\_t * trusted\_cas, unsigned tcas\_size, unsigned int flags, unsigned int * verify);**

# [ARGUMENTS](#ARGUMENTS)

[gnutls\_x509\_crl\_t crl](#gnutls_x509_crl_t)

is the crl to be verified

[const gnutls\_x509\_crt\_t * trusted\_cas](#const)

is a certificate list that is considered to be trusted one

[unsigned tcas\_size](#unsigned)

holds the number of CA certificates in CA\_list

[unsigned int flags](#unsigned~2)

Flags that may be used to change the verification algorithm. Use OR of the gnutls\_certificate\_verify\_flags enumerations.

[unsigned int * verify](#unsigned~3)

will hold the crl verification output.

# [DESCRIPTION](#DESCRIPTION)

This function will try to verify the given crl and return its verification status. See **gnutls\_x509\_crt\_list\_verify()** for a detailed description of return values. Note that since GnuTLS 3.1.4 this function includes the time checks.

Note that value in *verify* is set only when the return value of this function is success (i.e, failure to trust a CRL a certificate does not imply a negative return value).

Before GnuTLS 3.5.7 this function would return zero or a positive number on success.

# [RETURNS](#RETURNS)

On success, **GNUTLS\_E\_SUCCESS** (0), otherwise a negative error value.
