Pass in the name of the variable to store the binary data in as an  
argument to your function.  Then use an ExternalString and  
SetVariableEx.  For example, to assign the contents of a HANDLE  
containing PNG data you would do something like this:

ExternalString theExternalString.buffer = *thePNGHandle;
theExternalString.length = GetHandleSize(thePNGHandle);
SetVariableEx( p_arguments[0], "", &theExternalString, &r_success);
