-/* This file is an ugly hack to get GPGME working with Qt on Windows
- targets. On Windows, you can not select() on file descriptors.
-
- The only way to check if there is something to read is to read
- something. This means that GPGME can not let Qt check for data
- without letting Qt also handle the data on Windows targets.
-
- The ugly consequence is that we need to work on QIODevices in
- GPGME, creating a Qt dependency. Also, we need to export an
- interface for the application to get at GPGME's QIODevices. There
- is no good way to abstract all this with callbacks, because the
- whole thing is also interconnected with the creation of pipes and
- child processes.
-
- The following rule applies only to this I/O backend:
-
- * ALL operations must use the user defined event loop. GPGME can
- not anymore provide its own event loop. This is mostly a sanity
- requirement: Although we have in theory all information we need to
- make the GPGME W32 code for select still work, it would be a big
- complication and require changes throughout GPGME.
-
- Eventually, we probably have to bite the bullet and make some
- really nice callback interfaces to let the user control all this at
- a per-context level. */
