if(b) should do it. shared_ptr has an implicit conversion to bool (sort of).

I need some help in testing for the condition of whether a shared_ptr has been assigned. In the following example, the "if( b != NULL ) does not work. How would I do this test?

typedef boost::shared_ptr<int> IPtr;

int i( 0 ); IPtr a( i ); IPtr b;

if( some condition ) b = a;

if( b != NULL ) { // How should this really be coded? }

Best Regards,

Steve
