Declaration

gboolean
g_output_stream_flush (
  GOutputStream* stream,
  GCancellable* cancellable,
  GError** error
)

Description

Forces a write of all user-space buffered data for the given stream. Will block during the operation. Closing the stream will implicitly cause a flush.

This function is optional for inherited classes.

If cancellable is not NULL, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error G_IO_ERROR_CANCELLED will be returned.

Parameters

cancellable

Type: GCancellable

Optional cancellable object.

The argument can be NULL.

The data is owned by the caller of the function.

error

Type: GError **

The return location for an error.

The argument can be NULL.

The argument will be set to NULL by the function if there are no errors.

In case of error, the argument will be set and the caller will take ownership of the data, and be responsible for freeing it.

Return value

Type: gboolean

TRUE on success, FALSE on error.
