OCI Functions for C

Hi,

I have a query like this :
"SELECT ename FROM emp";
I use ofen( ) to fetch one or multiple rows but I don't know the length of string returned.
How I can obtain this information, in which OCI functions ? Example :

	Column ename (dbsize=10).
	When I fetch, data='SMITH     '
	How I can obtain length=5 ?
