Changes the current working directory to the open directory handle. Corresponds to "fchdir" in libc.
This modifies global process state and can have surprising effects in multithreaded applications. Most applications and especially libraries should not call this function as a general rule, however it can have use cases in, for example, implementing a shell, or child process execution.
Calling this function makes code less portable and less reusable.
pub fn setCurrentDir(io: Io, dir: Io.Dir) !void
pub fn setCurrentDir(io: Io, dir: Io.Dir) !void {
return io.vtable.processSetCurrentDir(io.userdata, dir);
}
