Enumeration

GioPollableReturn

Declaration

enum Gio.PollableReturn

Description [src]

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.
