Return value for various IO operations that signal errors via the
return value and not necessarily via a #GError.
This enum exists to be able to return errors to callers without having to
allocate a #GError. Allocating #GErrors can be quite expensive for
regularly happening errors like %G_IO_ERROR_WOULD_BLOCK.
In case of %G_POLLABLE_RETURN_FAILED a #GError should be set for the
operation to give details about the error that happened.
