# gnutls\_x509\_crt\_list\_import\_url(3)

API function

## NAME

gnutls\_x509\_crt\_list\_import\_url - API function

## SYNOPSIS

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

**int gnutls\_x509\_crt\_list\_import\_url(gnutls\_x509\_crt\_t \*\*** *certs***, unsigned int \*** *size***, const char \*** *url***, gnutls\_pin\_callback\_t** *pin\_fn***, void \*** *pin\_fn\_userdata***, unsigned int** *flags***);**

## ARGUMENTS

- gnutls\_x509\_crt\_t \*\* certs

  Will hold the allocated certificate list.

- unsigned int \* size

  It will contain the size of the list.

- const char \* url

  A PKCS 11 url

- gnutls\_pin\_callback\_t pin\_fn

  a PIN callback if not globally set

- void \* pin\_fn\_userdata

  parameter for the PIN callback

- unsigned int flags

  One of GNUTLS\_PKCS11\_OBJ\_\* flags for PKCS**11** URLs or zero otherwise

## DESCRIPTION

This function will import a certificate chain present in a PKCS**11** token or any type of back-end that supports URLs. The certificates must be deinitialized afterwards using **gnutls\_x509\_crt\_deinit()** and the returned pointer must be freed using **gnutls\_free()**.

The URI provided must be the first certificate in the chain; subsequent certificates will be retrieved using **gnutls\_pkcs11\_get\_raw\_issuer()** or equivalent functionality for the supported URI.

## RETURNS

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

## SINCE

3\.6.3
