Blanks vs: Nulls

I'm relatively new to Pro*C programming. In the following example:

char name[21]; EXEC SQL SELECT 'John Doe' INTO :name FROM DUAL;

"John Doe" is in positions 0-7, blanks in 8-19, and a null in 20. I would really prefer the null to be in position 8 and I don't care what's after that. I wrote a trim function to do that. If I forget to trim and insert the data into an Oracle table, it creates problems.

Is there a better technique?
