@deftypefun {int} {gnutls_pem_base64_encode2} (const char * @var{header}, const gnutls_datum_t * @var{data}, gnutls_datum_t * @var{result})

@var{header}: is a message to be put in the encoded header (may be @code{NULL} )

@var{data}: contains the raw data

@var{result}: will hold the newly allocated encoded data

This function will convert the given data to printable data, using

the base64 encoding.  This is the encoding used in PEM messages.

This function will allocate the required memory to hold the encoded

data.

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_encode_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
