enum Gio::PollableReturn


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.
