Hi,

I have some code that creates a temp file, writes to it and then calls
chmod(...) to make sure that the file has 0644 permissions.

// -------------
// pseudo code
//
$tmpfname = 'xyx'; // come from another function.

if (!($fd = @fopen($tmpfname, 'wb')))
{
return false;
}

fwrite($fd, $data ); // the data comes from another function has well.
no warnings given.
fclose($fd); // no warnings given.
chmod( $tmpfname, 0644 ); <!-- error here with "No such file or directory"
// -------------

The issue I have is that it works _sometimes_, in fact, 99% of the time
it works.
But from time to time the log reports that the file does not exist.

But how it is possible, if the file opened successfully with fopen( ... )

I wonder if the problem is partly because I am using @fopen(...) rather
than fopen(...), (I don't need to suppress the warnings).

But in that case fwrite(...) and fclose(...) would also report
errors/warnings.

Any suggestions as to why chmod(...), (and a subsequent rename(...) )
would sometimes not work.

Thanks

Simon
