llvm-mirror/lib/Fuzzer/FuzzerIO.h
Marcos Pividori 0e996298b5 [libFuzzer] Properly use Handle instead of FD on Windows.
For Windows, sanitizers work with Handles, not with posix file descriptors,
because they use the windows-specific API. So we need to convert the fds to
handles before passing them to the sanitizer library.
After this change, close_fd_mask is fixed for Windows (this fix some tests too).
