@deftypefun {int} {gnutls_pem_base64_decode} (const char * @var{header}, const gnutls_datum_t * @var{b64_data}, unsigned char * @var{result}, size_t * @var{result_size})
@var{header}: A null terminated string with the PEM header (eg. CERTIFICATE)

@var{b64_data}: contain the encoded data

@var{result}: the place where decoded data will be copied

@var{result_size}: holds the size of the result

This function will decode the given encoded data.  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.

@strong{Returns:} On success @code{GNUTLS_E_SUCCESS}  (0) is returned,
@code{GNUTLS_E_SHORT_MEMORY_BUFFER}  is returned if the buffer given is
not long enough, or 0 on success.
