I would like to open a file before I enter a function and be able to write to it while I'm in the function.  I'm not having any luck.  Shared? Global? Pass a pointer to the funcion?

auto fout = File("myfile.csv", "w"); is what I'm currently using.

Thanks for any assistance.

You should be able to just pass fout to a function normally:

void writeTo(File fout) {
   fout.writeln("info,here,etc");
}

void main() {
   auto fout = File("myfile.csv", "w");
   writeTo(fout);
}

import std.stdio;

void foo(File file)
{
    file.writeln("my csv\n");
}

void main()
{
    auto fout = File("myfile.csv", "w");
    foo(fout);
}
