Function Logic:

Function body:

hzEcode Base64Encode (hzChain& Encoded, const char* dir, const char* fname)
{
   //  Category: Codec
   //  
   //  Encode the contents of the file with the supplied path, from 7-Bit ASCII to Base64. The encoded data is then in a hzChain instance.
   //  
   //  Arguments: 1) Encoded The chain to contain the encoded data
   //     2) dir  The directory of the file containing the 7-Bit ASCII data to encode
   //     3) fname The file name within the directory
   //  
   //  Returns: E_ARGUMENT If either the directory or filename are not supplied
   //  E_NOTFOUND  If the filepath specified does not exist as a directory entry of any kind
   //  E_TYPE      If the filepath names a directory entry that is not a file
   //  E_NODATA    If the filepath is a file but empty
   //  E_OPENFAIL  If the file specified could not be opened for reading
   //  E_OK        If the input stream was opened and the content encoded
