API function

## NAME

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

## 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

- gnutls\_x509\_trust\_list\_t list

  The list

- gnutls\_x509\_crt\_t \* cert\_list

  is the certificate list to be verified

- unsigned int cert\_list\_size

  is the certificate list size

- unsigned int flags

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

- unsigned int \* voutput

  will hold the certificate verification output.

- gnutls\_verify\_output\_function func

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

## 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

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

## SINCE

3\.0
