Implements

Constructors

g_data_output_stream_new

Creates a new data output stream for base_stream.

Instance methods

g_data_output_stream_get_byte_order

Gets the byte order for the stream.

g_data_output_stream_put_byte

Puts a byte into the output stream.

g_data_output_stream_put_int16

Puts a signed 16-bit integer into the output stream.

g_data_output_stream_put_int32

Puts a signed 32-bit integer into the output stream.

g_data_output_stream_put_int64

Puts a signed 64-bit integer into the stream.

g_data_output_stream_put_string

Puts a string into the output stream.

g_data_output_stream_put_uint16

Puts an unsigned 16-bit integer into the output stream.

g_data_output_stream_put_uint32

Puts an unsigned 32-bit integer into the stream.

g_data_output_stream_put_uint64

Puts an unsigned 64-bit integer into the stream.

g_data_output_stream_set_byte_order

Sets the byte order of the data output stream to order.

Methods inherited from GFilterOutputStream (3)
g_filter_output_stream_get_base_stream

Gets the base stream for the filter stream.

g_filter_output_stream_get_close_base_stream

Returns whether the base stream will be closed when stream is closed.

g_filter_output_stream_set_close_base_stream

Sets whether the base stream will be closed when stream is closed.

Methods inherited from GOutputStream (31)
g_output_stream_clear_pending

Clears the pending flag on stream.

g_output_stream_close

Closes the stream, releasing resources related to it.

g_output_stream_close_async

Requests an asynchronous close of the stream, releasing resources related to it. When the operation is finished callback will be called. You can then call g_output_stream_close_finish() to get the result of the operation.

g_output_stream_close_finish

Closes an output stream.

g_output_stream_flush

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.

g_output_stream_flush_async

Forces an asynchronous write of all user-space buffered data for the given stream. For behaviour details see g_output_stream_flush().

g_output_stream_flush_finish

Finishes flushing an output stream.

g_output_stream_has_pending

Checks if an output stream has pending actions.

g_output_stream_is_closed

Checks if an output stream has already been closed.

g_output_stream_is_closing

Checks if an output stream is being closed. This can be used inside e.g. a flush implementation to see if the flush (or other i/o operation) is called from within the closing operation.

Available since: 2.24

g_output_stream_printf

This is a utility function around g_output_stream_write_all(). It uses g_strdup_vprintf() to turn format and @… into a string that is then written to stream.

Available since: 2.40

g_output_stream_set_pending

Sets stream to have actions pending. If the pending flag is already set or stream is closed, it will return FALSE and set error.

g_output_stream_splice

Splices an input stream into an output stream.

g_output_stream_splice_async

Splices a stream asynchronously. When the operation is finished callback will be called. You can then call g_output_stream_splice_finish() to get the result of the operation.

g_output_stream_splice_finish

Finishes an asynchronous stream splice operation.

g_output_stream_vprintf

This is a utility function around g_output_stream_write_all(). It uses g_strdup_vprintf() to turn format and args into a string that is then written to stream.

Available since: 2.40

g_output_stream_write

Tries to write count bytes from buffer into the stream. Will block during the operation.

g_output_stream_write_all

Tries to write count bytes from buffer into the stream. Will block during the operation.

g_output_stream_write_all_async

Request an asynchronous write of count bytes from buffer into the stream. When the operation is finished callback will be called. You can then call g_output_stream_write_all_finish() to get the result of the operation.

Available since: 2.44

g_output_stream_write_all_finish

Finishes an asynchronous stream write operation started with g_output_stream_write_all_async().

Available since: 2.44

g_output_stream_write_async

Request an asynchronous write of count bytes from buffer into the stream. When the operation is finished callback will be called. You can then call g_output_stream_write_finish() to get the result of the operation.

g_output_stream_write_bytes

A wrapper function for g_output_stream_write() which takes a GBytes as input. This can be more convenient for use by language bindings or in other cases where the refcounted nature of GBytes is helpful over a bare pointer interface.

g_output_stream_write_bytes_async

This function is similar to g_output_stream_write_async(), but takes a GBytes as input. Due to the refcounted nature of GBytes, this allows the stream to avoid taking a copy of the data.

Methods inherited from GObject (43)
Methods inherited from GSeekable (5)
g_seekable_can_seek

Tests if the stream supports the GSeekableIface.

g_seekable_can_truncate

Tests if the length of the stream can be adjusted with g_seekable_truncate().

g_seekable_seek

Seeks in the stream by the given offset, modified by type.

g_seekable_tell

Tells the current position within the stream.

g_seekable_truncate

Sets the length of the stream to offset. If the stream was previously larger than offset, the extra data is discarded. If the stream was previously shorter than offset, it is extended with NUL (‘\0’) bytes.

Properties

Gio.DataOutputStream:byte-order

Determines the byte ordering that is used when writing multi-byte entities (such as integers) to the stream.
