Hi,

I am trying to work out if I need to call close on a fstream object if the intial open failed.

i.e.

std::fstream strm;
strm.open( "filename" );

if( ! strm.fail() )
{
    // Do something

    strm.close();  // [1]
}

strm.close();  // [2]

Where should close be called here - should it always be called [2] or only if the open succeeds[1]?

I may be going over the top here, but coming from the Windows API way of typically doing this I have CloseHandle( ... ); embedded in my mind :-)
