Class
GioBufferedOutputStream
Description [src]
class Gio.BufferedOutputStream : Gio.FilterOutputStream {
parent_instance: GFilterOutputStream,
priv: GBufferedOutputStreamPrivate*
}Buffered output stream implements GFilterOutputStream and provides
for buffered writes.
By default, GBufferedOutputStream‘s buffer size is set at 4 kilobytes.
To create a buffered output stream, use g_buffered_output_stream_new(),
or g_buffered_output_stream_new_sized() to specify the buffer’s size
at construction.
To get the size of a buffer within a buffered input stream, use
g_buffered_output_stream_get_buffer_size(). To change the size of a
buffered output stream’s buffer, use
g_buffered_output_stream_set_buffer_size(). Note that the buffer’s
size cannot be reduced below the size of the data within the buffer.
Constructors
g_buffered_output_stream_new
Creates a new buffered output stream for a base stream.
g_buffered_output_stream_new_sized
Creates a new buffered output stream with a given buffer size.
Instance methods
g_buffered_output_stream_get_auto_grow
Checks if the buffer automatically grows as data is added.
g_buffered_output_stream_get_buffer_size
Gets the size of the buffer in the stream.
g_buffered_output_stream_set_auto_grow
Sets whether or not the stream‘s buffer should automatically grow.
If auto_grow is true, then each write will just make the buffer
larger, and you must manually flush the buffer to actually write out
the data to the underlying stream.
g_buffered_output_stream_set_buffer_size
Sets the size of the internal buffer to size.
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.
