Class

GioBufferedInputStream

Description [src]

class Gio.BufferedInputStream : Gio.FilterInputStream
  implements Gio.Seekable {
  /* No available fields */
}

Constructors

g_buffered_input_stream_new

Creates a new GInputStream from the given base_stream, with a buffer set to the default size (4 kilobytes).

Instance methods

g_buffered_input_stream_fill_async

Reads data into stream‘s buffer asynchronously, up to count size.io_priority can be used to prioritize reads. For the synchronous version of this function, see g_buffered_input_stream_fill().

g_buffered_input_stream_peek_buffer

Returns the buffer with the currently available bytes. The returned buffer must not be modified and will become invalid when reading from the stream or filling the buffer.

g_buffered_input_stream_set_buffer_size

Sets the size of the internal buffer of stream to size, or to the size of the contents of the buffer. The buffer can never be resized smaller than its current contents.

Methods inherited from GInputStream (19)

g_input_stream_close

Closes the stream, releasing resources related to it.

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

g_input_stream_close_finish

Finishes closing a stream asynchronously, started from g_input_stream_close_async().

g_input_stream_has_pending

Checks if an input stream has pending actions.

g_input_stream_is_closed

Checks if an input stream is closed.

g_input_stream_read

Tries to read count bytes from the stream into the buffer starting atbuffer. Will block during this read.

g_input_stream_read_all

Tries to read count bytes from the stream into the buffer starting atbuffer. Will block during this read.

g_input_stream_read_all_async

Request an asynchronous read of count bytes from the stream into the buffer starting at buffer.

since: 2.44

g_input_stream_read_all_finish

Finishes an asynchronous stream read operation started withg_input_stream_read_all_async().

since: 2.44

g_input_stream_read_async

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

g_input_stream_read_bytes

Like g_input_stream_read(), this tries to read count bytes from the stream in a blocking fashion. However, rather than reading into a user-supplied buffer, this will create a new GBytes containing the data that was read. This may be easier to use from language bindings.

since: 2.34

g_input_stream_read_bytes_async

Request an asynchronous read of count bytes from the stream into a new GBytes. When the operation is finished callback will be called. You can then call g_input_stream_read_bytes_finish() to get the result of the operation.

since: 2.34

g_input_stream_read_bytes_finish

Finishes an asynchronous stream read-into-GBytes operation.

since: 2.34

g_input_stream_read_finish

Finishes an asynchronous stream read operation.

g_input_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 seterror.

g_input_stream_skip

Tries to skip count bytes from the stream. Will block during the operation.

g_input_stream_skip_async

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

g_input_stream_skip_finish

Finishes a stream skip operation.

Please see GObject for a full list of methods.

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.

GObject::notify

The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.
