NAME
       gnutls_system_key_iter_get_info - API function
SYNOPSIS
       #include <gnutls/system-keys.h>
       int   gnutls_system_key_iter_get_info(gnutls_system_key_iter_t   *  iter,  unsigned  cert_type,  char  **
       cert_url, char ** key_url, char ** label, gnutls_datum_t * der, unsigned int flags);
ARGUMENTS
       gnutls_system_key_iter_t * iter
                   an iterator of the system keys (must be set to NULL initially)
       unsigned cert_type
                   A value of gnutls_certificate_type_t which indicates the type of certificate to look for
       char ** cert_url
                   The certificate URL of the pair (may be NULL)
       char ** key_url
                   The key URL of the pair (may be NULL)
       char ** label
                   The friendly name (if any) of the pair (may be NULL)
       gnutls_datum_t * der
                   if non-NULL the DER data of the certificate
       unsigned int flags
                   should be zero
DESCRIPTION
       This function will return on each call a certificate and key pair URLs, as well  as  a  label  associated
       with   them,   and   the  DER-encoded  certificate.  When  the  iteration  is  complete  it  will  return
       GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE.
       Typically  cert_type should be GNUTLS_CRT_X509.
       All values set are allocated and must be cleared using gnutls_free(),
RETURNS
       On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error value.
