[Vortex] Sending binary data

[Yourch, Chris]

So, "under the covers" a stream of byte's are actually sent? i.e. the
const char * is cast to an unsigned char * and then sent?

If it takes arbitrary binary data, the type really should be "const  
void*".

Just cast your data pointer, whatever type it may be, to (const char*)  
to pass it to the function.
