get_chunk

Gets a [struct@GLib.

Bytes] containing data from this starting at offset.

The size of the returned chunk is unspecified. You can iterate through the entire body by first calling [method@MessageBody.get_chunk] with an offset of 0, and then on each successive call, increment the offset by the length of the previously-returned chunk.

If offset is greater than or equal to the total length of this, then the return value depends on whether or not [method@MessageBody.complete] has been called or not; if it has, then [method@MessageBody.get_chunk] will return a 0-length chunk (indicating the end of this). If it has not, then [method@MessageBody.get_chunk] will return null (indicating that this may still potentially have more data, but that data is not currently available).

Parameters:

this	a MessageBody
offset	an offset

Returns:

a Bytes
