@deftypefun {int} {gnutls_x509_ext_export_proxy} (int @var{pathLenConstraint}, const char * @var{policyLanguage}, const char * @var{policy}, size_t @var{sizeof_policy}, gnutls_datum_t * @var{ext})
@var{pathLenConstraint}: non-negative error codes indicate maximum length of path,
and negative error codes indicate that the pathLenConstraints field should
not be present.

@var{policyLanguage}: OID describing the language of  @code{policy} .

@var{policy}: uint8_t byte array with policy language, can be @code{NULL} 

@var{sizeof_policy}: size of  @code{policy} .

@var{ext}: The DER-encoded extension data; must be freed using @code{gnutls_free()} .

This function will convert the parameters provided to a proxyCertInfo extension.

The  @code{ext} data will be allocated using
@code{gnutls_malloc()} .

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

@strong{Since:} 3.3.0
