# [NAME](#NAME)

gnutls\_x509\_trust\_list\_iter\_get\_ca - API function

# [SYNOPSIS](#SYNOPSIS)

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

**int gnutls\_x509\_trust\_list\_iter\_get\_ca(gnutls\_x509\_trust\_list\_t list, gnutls\_x509\_trust\_list\_iter\_t * iter, gnutls\_x509\_crt\_t * crt);**

# [ARGUMENTS](#ARGUMENTS)

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

The list

[gnutls\_x509\_trust\_list\_iter\_t * iter](#gnutls_x509_trust_list_iter_t)

A pointer to an iterator (initially the iterator should be **NULL**)

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

where the certificate will be copied

# [DESCRIPTION](#DESCRIPTION)

This function obtains a certificate in the trust list and advances the iterator to the next certificate. The certificate returned in *crt* must be deallocated with **gnutls\_x509\_crt\_deinit()**.

When past the last element is accessed **GNUTLS\_E\_REQUESTED\_DATA\_NOT\_AVAILABLE** is returned and the iterator is reset.

The iterator is deinitialized and reset to **NULL** automatically by this function after iterating through all elements until **GNUTLS\_E\_REQUESTED\_DATA\_NOT\_AVAILABLE** is returned. If the iteration is aborted early, it must be manually deinitialized using **gnutls\_x509\_trust\_list\_iter\_deinit()**.

# [RETURNS](#RETURNS)

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