ret = ioctl(fd, SPI_IOC_MESSAGE(1), &tr);

<pre>
char * CLASS_LCM1602::BuildMessage(char *&title, int value) {

	// convert int to char
	char buffer[100];
	snprintf(buffer, sizeof(buffer), "%d", value);
#ifdef DEBUG
	cout << " conversion int to char buffer " << +buffer << endl; //TOK 
#endif

	char FullMessage[100];
	// why is this needed ?? strcat won't execute without strcpy first
	strcpy(FullMessage, title);
	cout << "title copy " << FullMessage << endl;
	//append buffer
	strcat(FullMessage, buffer);
	cout << "full message " << FullMessage << endl; // TOK 

this is where I need some help 
this does not makes sense to me 
it compiles , does not execute 

 	strcpy(title, FullMessage);
	cout << "title " << title << endl;

	exit(1);  // temp exit 

	return FullMessage;  // return not used , need to compile 
}

<pre>	
        char *title = "NEW TEST";
	int  value  = 100;
	char *message = i2c.BuildMessage(title, value); // message not used for now 

here is the desired result code 
never gets here 	

	cout << " pass full message "<< +title << endl;

#endif
