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.
