How to determine the size of long raw data types?

Hi,

Does anyone knows how to determine the size of LONG RAW data (blob), before downloading it using Pro*C?

I need this information because I would like to use the malloc() function to allocate exactly the needed memory. The Oracle Pro*C/C++ Precompiler Manual use only this kind of allocation (which is not really dynamic):  

    typedef unsigned char *my_raw;

    EXEC SQL TYPE my_raw IS VARRAW(4000) REFERENCE;

    my_raw graphics_buffer;

    graphics_buffer = (my_raw) malloc(4004);

The problem is, if I have a blob larger than 4000 bytes I need to change the source code and compile it once again.

Thanks in advance
