NAME         top

       gnutls_certificate_get_x509_crt - API function

SYNOPSIS         top

       #include <gnutls/gnutls.h>

       int gnutls_certificate_get_x509_crt(gnutls_certificate_credentials_t
       res, unsigned index, gnutls_x509_crt_t ** crt_list, unsigned *

ARGUMENTS         top

       gnutls_certificate_credentials_t res
                   is a gnutls_certificate_credentials_t type.

       unsigned index
                   The index of the certificate list to obtain.

       gnutls_x509_crt_t ** crt_list
                   Where to store the certificate list.

       unsigned * crt_list_size
                   Will hold the number of certificates.

DESCRIPTION         top

       Obtains a X.509 certificate list that has been stored in  res with
       one of gnutls_certificate_set_x509_key(),
       gnutls_certificate_set_key(), gnutls_certificate_set_x509_key_file(),
       gnutls_certificate_set_x509_key_mem(), or
       gnutls_certificate_set_x509_key_mem2(). Each certificate in the
       returned certificate list must be deallocated with
       gnutls_x509_crt_deinit(), and the list itself must be freed with

       The  index matches the return value of
       gnutls_certificate_set_x509_key() and friends functions, when the
       GNUTLS_CERTIFICATE_API_V2 flag is set.

       If there is no certificate with the given index,
       GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE is returned. If the certificate
       with the given index is not a X.509 certificate,
       GNUTLS_E_INVALID_REQUEST is returned. The returned certificates must
       be deinitialized after use, and the  crt_list pointer must be freed
       using gnutls_free().

RETURNS         top

       GNUTLS_E_SUCCESS (0) on success, or a negative error code.
