@deftypefun {int} {gnutls_pem_base64_decode2} (const char * @var{header}, const gnutls_datum_t * @var{b64_data}, gnutls_datum_t * @var{result})

@var{header}: The PEM header (eg. CERTIFICATE)

@var{b64_data}: contains the encoded data

@var{result}: the location of decoded data

This function will decode the given encoded data. The decoded data

will be allocated, and stored into result.  If the header given is

non null this function will search for "-----BEGIN header" and

decode only this part. Otherwise it will decode the first PEM

packet found.

You should use @code{gnutls_free()}  to free the returned data.

Note, that prior to GnuTLS 3.4.0 this function was available

under the name @code{gnutls_pem_base64_decode_alloc()} . There is

compatibility macro pointing to this function.

@strong{Returns:} On success, @code{GNUTLS_E_SUCCESS}  (0) is returned, otherwise

an error code is returned.

@strong{Since:} 3.4.0
