Method

GioSimpleAsyncResultset_check_cancellable

deprecated: 2.46 since: 2.32

Declaration

void
g_simple_async_result_set_check_cancellable (
  GSimpleAsyncResult* simple,
  GCancellable* check_cancellable
)

Description

Sets a GCancellable to check before dispatching results.

This function has one very specific purpose: the provided cancellable is checked at the time of g_simple_async_result_propagate_error() If it is cancelled, these functions will return an “Operation was cancelled” error (G_IO_ERROR_CANCELLED).

Implementors of cancellable asynchronous functions should use this in order to provide a guarantee to their callers that cancelling an async operation will reliably result in an error being returned for that operation (even if a positive result for the operation has already been sent as an idle to the main context to be dispatched).

The checking described above is done regardless of any call to the unrelated g_simple_async_result_set_handle_cancellation() function.

Available since: 2.32

Deprecated since: 2.46

Use GTask instead.

Parameters

check_cancellable

Type: GCancellable

A GCancellable to check, or NULL to unset.

The argument can be NULL.

The data is owned by the caller of the function.
