#### Instance methods

##### Methods inherited from GInputStream (19)

###### g_input_stream_clear_pending

Clears the pending flag on `stream`.

since: 2.0

###### g_input_stream_close

Closes the stream, releasing resources related to it.

since: 2.0

###### 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.

since: 2.0

###### g_input_stream_close_finish

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

since: 2.0

###### g_input_stream_has_pending

Checks if an input stream has pending actions.

since: 2.0

###### g_input_stream_is_closed

Checks if an input stream is closed.

since: 2.0

###### g_input_stream_read

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

since: 2.0

###### g_input_stream_read_all

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

since: 2.0

###### g_input_stream_read_all_async

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

unstable since: 2.44

###### g_input_stream_read_all_finish

Finishes an asynchronous stream read operation started with g_input_stream_read_all_async().

unstable 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.

since: 2.0

###### 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.

unstable 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.

unstable since: 2.34

###### g_input_stream_read_bytes_finish

Finishes an asynchronous stream read-into-`GBytes` operation.

unstable since: 2.34

###### g_input_stream_read_finish

Finishes an asynchronous stream read operation.

since: 2.0

###### 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`.

since: 2.0

###### g_input_stream_skip

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

since: 2.0

###### 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.

since: 2.0

###### g_input_stream_skip_finish

Finishes a stream skip operation.

since: 2.0

##### Methods inherited from GSeekable (5)

###### g_seekable_can_seek

###### g_seekable_seek

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

since: 2.0

###### g_seekable_tell

Tells the current position within the stream.

since: 2.0

###### 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.

since: 2.0
