No console, pipes, exec/spawning, or win32 window messages. Lookup of DNS records with
DnsQuery is also deprecated, and there's no replacement for that, afaict.
@pwithnall we discussed having a replacement for the
GIOChannel win32 window message integration, but after thinking about it, I realized that there is no replacement for that workflow, because with C++/WinRT you're supposed to use C++
coroutines, which do not map to the
GIOChannel model at all.
gmodule/uwp: Don't check for the targeted Windows version UWP APIs are only available when targeting Windows 8+ anyway, so `G_WINAPI_ONLY_APP` being set means Windows 8+ is being targeted. We don't need that extra check.
win_iconv: Use LoadPackagedLibrary when building UWP apps LoadLibrary is not available at all when building with `-DWINAPI_FAMILY=WINAPI_FAMILY_APP`.
gspawn: Do not allow spawning processes or making pipes on UWP _pipe(), _wspawn*() are not allowed on UWP apps, and will cause a Windows App Certification Kit error. Set errno as ENOSYS instead of EACCES so that it's slightly clearer to the user that they shouldn't use the gspawn API on UWP.
giowin32: Error on invalid usage of GIOChannels on UWP Win32 window handles and consoles do not exist on UWP apps, and the corresponding APIs are not allowed. They cause an error when running the Windows App Certification Kit. The console is gone, the APIs are gone, and there is no replacement. Win32 Windows are gone, and so is the event-based messaging system. There's a new model for handling user input in app windows, but it is only available in C++17/WinRT, so you cannot use that from C anyway, and we do not need to add a replacement for it in GIOChannel. Error out whenever possible when the user calls the GIOChannel API for either of those when glib is built for the Universal Windows Platform. This means we will print criticals and return a valid GIOChannel, but doing anything with it will fail and return GErrors.
glocalfile: Trash as a concept does not exist on UWP And the functions we use to implement `g_local_file_trash()` are not available on UWP either, so just return an error when it's called.
gresolver: DnsQuery is not available on UWP Return an error when looking up records when glib is built for UWP apps.
gdbusprivate: Disable console and win32 window usage on UWP These are not allowed when shipping a UWP app, and we use it all for debugging anyway.
