Raw Data

Raw data is used to store information that is platform-dependent or is inherently not alphanumeric.

In a text file, raw data is stored as hexadecimal strings prefixed by the characters ' 0x' . Strings of raw data are not padded in text files. However, your application may pad them if you wish.

In a binary file, raw data is stored as sequences of bytes, padded to a 4-byte boundary. The size of raw data is computed as follows (the computation differs from that for string in that raw data doesn't require a terminating \0):



 
    remainder = radDataSize % 4;

    pad = ( (remainder > 0) ? (4 - remainder) : 0 );

    size = radDataSize + pad;
