@deftypefun {int} {gnutls_x509_crq_export2} (gnutls_x509_crq_t @var{crq}, gnutls_x509_crt_fmt_t @var{format}, gnutls_datum_t * @var{out})
@var{crq}: should contain a @code{gnutls_x509_crq_t}  type

@var{format}: the format of output params. One of PEM or DER.

@var{out}: will contain a certificate request PEM or DER encoded

This function will export the certificate request to a PEM or DER
encoded PKCS10 structure.

The output buffer is allocated using @code{gnutls_malloc()} .

If the structure is PEM encoded, it will have a header of "BEGIN
NEW CERTIFICATE REQUEST".

@strong{Returns:} On success, @code{GNUTLS_E_SUCCESS}  (0) is returned, otherwise a
negative error value.
