- * parameter is not zero, it specifies the length of the source data. If it
- * is zero, the source data is assumed to be null-terminated, and PL_strlen

- * null, it is assumed to point to a buffer of sufficient size (which may be
- * calculated: ((srclen + 2)/3)*4) into which the encoded data is placed
- * (without any termination). If the "dest" parameter is null, a buffer is
- * allocated from the heap to hold the encoded data, and the result *will*
- * be terminated with an extra null character. It is the caller's
- * responsibility to free the result when it is allocated. A null is returned
- * if the allocation fails.
