# [NAME](#NAME)

gnutls\_x509\_trust\_list\_verify\_crt - API function

# [SYNOPSIS](#SYNOPSIS)

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

**int gnutls\_x509\_trust\_list\_verify\_crt(gnutls\_x509\_trust\_list\_t list, gnutls\_x509\_crt\_t * cert\_list, unsigned int cert\_list\_size, unsigned int flags, unsigned int * voutput, gnutls\_verify\_output\_function func);**

# [ARGUMENTS](#ARGUMENTS)

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

The list

[gnutls\_x509\_crt\_t * cert\_list](#gnutls_x509_crt_t)

is the certificate list to be verified

[unsigned int cert\_list\_size](#unsigned)

is the certificate list size

[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 * voutput](#unsigned~3)

will hold the certificate verification output.

[gnutls\_verify\_output\_function func](#gnutls_verify_output_function)

If non-null will be called on each chain element verification with the output.

# [DESCRIPTION](#DESCRIPTION)

This function will try to verify the given certificate and return its status. The *voutput* parameter will hold an OR'ed sequence of **gnutls\_certificate\_status\_t** flags.

The details of the verification are the same as in **gnutls\_x509\_trust\_list\_verify\_crt2()**.

# [RETURNS](#RETURNS)

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