#### Implements

#### Constructors

###### camel_stream_new

Creates a `CamelStream` as a thin wrapper for `base_stream`.

since: 3.12

#### Instance methods

###### camel_stream_close

Closes the stream.

###### camel_stream_eos

Tests if there are bytes left to read on the `stream` object.

###### camel_stream_flush

Flushes any buffered data to the stream’s backing store. Only meaningful for writable streams.

###### camel_stream_read

Attempts to read up to `n` bytes from `stream` into `buffer`.

###### camel_stream_ref_base_stream

Returns the `GIOStream` for `stream`. This is only valid if `stream` was created with camel_stream_new(). For all other `CamelStream` subclasses this function returns `NULL`.

since: 3.12

###### camel_stream_set_base_stream

Replaces the `GIOStream` passed to `camel_stream_new()` with `base_stream`. The new `base_stream` should wrap the original `GIOStream`, such as when adding Transport Layer Security after issuing a STARTTLS command.

since: 3.12

###### camel_stream_write

Attempts to write up to `n` bytes of `buffer` into `stream`.

###### camel_stream_write_string

Writes the string to the stream.

###### camel_stream_write_to_stream

Write all of a stream (until eos) into another stream, in a blocking fashion.

##### Methods inherited from GObject (43)

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.

#### Properties

###### Camel.Stream:base-stream

The base `GIOStream`.

#### 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.
