Yes, see file plugin

EXPORT(int) primitiveFileRead(void) {
     size_t byteSize;
     size_t count;
     int array;
     SQFile * file;
     int bytesRead;
     size_t startIndex;
     char * arrayIndex;
     int objectPointer;

	count =  
interpreterProxy->positive32BitValueOf(interpreterProxy- >stackValue(0));
	startIndex =  
interpreterProxy->positive32BitValueOf(interpreterProxy- >stackValue(1));


In your plugin say  it is a Oops parameter, then invoke  
positive32BitValueOf against it to get the integer.
