Warning
  Symbols prefixed with either RBIMPL or rbimpl are implementation details. Don't take them as canon. They could rapidly appear then vanish. The name (path) of this header file is also an implementation detail. Do not expect it to persist at the place it is now. Developers are free to move it anywhere anytime at will.

Note
  To ruby-core: remember that this header can be possibly recursively included from extension libraries written in C++. Do not expect for instance __VA_ARGS__ is always available. We assume C99 for ruby itself but we don't assume languages of extension libraries. They could be written in C++98.

## Function Documentation

## ◆ rb_dir_getwd()

VALUE rb_dir_getwd | ( | void |  | ) |

Queries the path of the current working directory of the current process.

Returns
  An instance of rb_cString that holds the working directory.

Note
  The returned string is in "filesystem" encoding. Most notably on Linux this is an alias of default external encoding. Most notably on Windows it can be an alias of OS codepage.
