-/* Handle translation. On W32, we provide handle values on the
- command line directly and using special file names such as
- "-&HANDLE". However, in GPGME we can not directly inherit the
- handles as this may interfere with other components in a
- multithreaded application. Thus, we inject the handles after
- creating the GPG process. The problem is that the handle numbers
- change at injection, but it is too late to change the command line.
- Hence this hack, which allows us to translate the handle values
- in the command line to their new values after injection.
-
- Handles that must be translated are those occuring in special file
- names (see iobuf.c::check_special_filename) as well as those given
- directly to options (see translate_sys2libc_fd_int). */
