Method Stdio.Fd()->dup2()

Method dup2

int Stdio.Fd()->dup2(object(Stdio.File) to)

Description

Duplicate a file over another.

This function works similarly to assign(), but instead of making the argument a reference to the same file, it creates a new file with the same properties and places it in the argument.
