Class
GioInputStream
Description [src]
abstract class Gio.InputStream : GObject.Object
{
  /* No available fields */
}GInputStream is a base class for implementing streaming input.
It has functions to read from a stream (g_input_stream_read()),
to close a stream (g_input_stream_close()) and to skip some content
(g_input_stream_skip()).
To copy the content of an input stream to an output stream without
manually handling the reads and writes, use g_output_stream_splice().
See the documentation for GIOStream for details of thread safety
of streaming APIs.
All of these functions have async variants too.
Instance methods
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_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_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_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.
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.
