[svn-r4605]

Browse Source 
Purpose:
    Bug fix

Description:
    Add the overloaded member function Attribute::getName to return
    the attribute name's length as in C API.  This functionality was
    missing.  Note that the current getName that returns "string"
    is not removed, for different way of using getName.

Platforms tested:
    SunOS 5.7 (arabica)
    Windows 98
