ofstream valid path and name

The following code writes to a file on either local disk to a remote disk (commented out code) on Windows 7 platform.

Code:

---

#include <iostream>
#include <fstream>
using namespace std;

int main ()
{
  ofstream outfile;
  outfile.open ("test.txt");
  //outfile.open ("\\\\server/temp/test.txt");
  outfile << "Hello world";
  outfile.close();
  return 0;
}

---

The documentation does not specify what is a valid filename (path and filename). For example, will the "\\\\server\temp" path work on all operating systems to access a samba share? Does the constructor accept forward and backward slashes as folder separator on all operating systems?

That is because a valid name depends on the operating system, and the C++ specification says nothing about what makes a file name valid.

I believe for standard C++ I/O functions, both forward and backward slashes are used as directory separators. For OS specific I/O functions (such as CreateFile), then the OS decides what is the directory separator.
