## Includes

    #include <telepathy-glib/text-mixin.h>

## Description

This mixin can be added to a channel GObject class to implement the text channel type in a general way. It implements the pending message queue and GetMessageTypes, so the implementation should only need to implement Send.

To use the text mixin, include a TpTextMixinClass somewhere in your class structure and a TpTextMixin somewhere in your instance structure, and call `tp_text_mixin_class_init()` from your class_init function, `tp_text_mixin_init()` from your init function or constructor, and `tp_text_mixin_finalize()` from your dispose or finalize function.

To use the text mixin as the implementation of TpSvcChannelTypeText, in the function you pass to G_IMPLEMENT_INTERFACE, you should first call `tp_text_mixin_iface_init()`, then call `tp_svc_channel_type_text_implement_send()` to register your implementation of the Send method.
