GioDataInputStream
Description [src]
class Gio.DataInputStream : Gio.BufferedInputStream
implements Gio.Seekable {
/* No available fields */
}Data input stream implements GInputStream and includes functions
for reading structured data directly from a binary input stream.
Instance methods
g_data_input_stream_read_line
Reads a line from the data input stream. Note that no encoding checks or conversion is performed; the input is not guaranteed to be UTF-8, and may in fact have embedded NUL characters.
g_data_input_stream_read_line_async
The asynchronous version of g_data_input_stream_read_line(). It is an error to have two outstanding calls to this function.
since: 2.20
g_data_input_stream_read_line_finish
Finish an asynchronous call started by
g_data_input_stream_read_line_async(). Note the warning about
string encoding in g_data_input_stream_read_line() applies here as well.
since: 2.20
g_data_input_stream_read_line_finish_utf8
Finish an asynchronous call started by g_data_input_stream_read_line_async().
since: 2.30
g_data_input_stream_read_line_utf8
Reads a UTF-8 encoded line from the data input stream.
since: 2.30
g_data_input_stream_read_until
Reads a string from the data input stream, up to the first occurrence of any of the stop characters.
deprecated: 2.56
g_data_input_stream_read_until_async
The asynchronous version of g_data_input_stream_read_until(). It is an error to have two outstanding calls to this function.
deprecated: 2.56 since: 2.20
g_data_input_stream_read_until_finish
Finish an asynchronous call started by g_data_input_stream_read_until_async().
deprecated: 2.56 since: 2.20
g_data_input_stream_read_upto
Reads a string from the data input stream, up to the first occurrence of any of the stop characters.
since: 2.26
g_data_input_stream_read_upto_async
The asynchronous version of g_data_input_stream_read_upto(). It is an error to have two outstanding calls to this function.
since: 2.26
g_data_input_stream_read_upto_finish
Finish an asynchronous call started by g_data_input_stream_read_upto_async().
since: 2.24
g_data_input_stream_set_byte_order
This function sets the byte order for the given stream. All subsequent
reads from the stream will be read in the given order.
Methods inherited from GBufferedInputStream (9)
g_buffered_input_stream_fill
Tries to read count bytes from the stream into the buffer.
Will block during this read.
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_fill_finish
Finishes an asynchronous read.
g_buffered_input_stream_get_available
Gets the size of the available data within the stream.
g_buffered_input_stream_get_buffer_size
Gets the size of the input buffer.
g_buffered_input_stream_peek
Peeks in the buffer, copying data of size count into buffer,
offset offset bytes.
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_read_byte
Tries to read a single byte from the stream or the buffer. Will block during this read.
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 GFilterInputStream (3)
g_filter_input_stream_get_base_stream
Gets the base stream for the filter stream.
g_filter_input_stream_get_close_base_stream
Returns whether the base stream will be closed when stream is closed.
g_filter_input_stream_set_close_base_stream
Sets whether the base stream will be closed when stream is closed.
Methods inherited from GInputStream (19)
g_input_stream_clear_pending
Clears the pending flag on stream.
g_input_stream_close
Closes the stream, releasing resources related to it.
g_input_stream_close_async
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 at
buffer. Will block during this read.
g_input_stream_read_all
Tries to read count bytes from the stream into the buffer starting at
buffer. 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 with
g_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 set
error.
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.
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.DataInputStream:byte-order
The :byte-order property determines the byte ordering that is used when reading multi-byte entities (such as integers) from the stream.
Gio.DataInputStream:newline-type
The :newline-type property determines what is considered as a line ending when reading complete lines from the stream.
Properties inherited from GBufferedInputStream (1)
Properties inherited from GFilterInputStream (2)
Gio.FilterInputStream:base-stream
The underlying base stream on which the I/O ops will be done.
Gio.FilterInputStream:close-base-stream
Whether the base stream should be closed when the filter stream is closed.
Signals
Signals inherited from GObject (1)
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.
