The scope of a file descriptor

Is the scope of a file descriptor limited to the subroutine/function
where the file is opened, or can it be passed as an argument to another
subroutine? I.e., is it possible to open a file in the main part of a
program and write/read the file from some subroutine? I'm looking for a
Fortran equivalent of doing the following in C++:

void some_output (fstream& fout, int x)
{
fout << x;
}

int main ()
{
fstream afile ("somefile.txt", ios::out);
some_output (afile, 5);
    afile.close();
}
