NAME

       gnutls_certificate_get_x509_crt - API function

SYNOPSIS

       #include <gnutls/gnutls.h>

       int  gnutls_certificate_get_x509_crt(gnutls_certificate_credentials_t res, unsigned index,
       gnutls_x509_crt_t ** crt_list, unsigned * crt_list_size);

ARGUMENTS

       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

       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_file2(),
       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 gnutls_free().

       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

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