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.

SINCE
