Enumeration
GioPollableReturn
since: 2.60
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.
