stdc++ fstream file permission

[Avner]

I have a C++ code which I want to upgrade to the standard C++

The code constructs a file and sets the file permission
The new iostream library does not include filebuf:penprot

The old ofstream constructor (<fstream.h>) accepts a third parameter (int
nProt = filebuf:penprot)

i.e. ofstream( const char* szName, int nMode = ios:ut, int nProt =
filebuf:penprot );

but the standard ofstream constructor (<fstream>) does not accept the third
parameter anymore.


How do I preserve the functionality to set the file permission?

Thanks,
Avner

As Victor replied to your earlier post - you can't (using the Std Lib).

You can use the POSIX open()/close() functions (available on all POSIX
compliant systems, Windows, unix, etc). To create the file with the
desired permissions, then use an ofstream to put data in the file.
