Public Attributes
int53	chat_id_
	Chat identifier.
int53	from_message_id_
	Identifier of the message starting from which history must be fetched; use 0 to get results from the last message.
int32	offset_
	Specify 0 to get results from exactly the from_message_id or a negative offset up to 99 to get additionally some newer messages.
int32	limit_
	The maximum number of messages to be returned; must be positive and can't be greater than 100. If the offset is negative, the limit must be greater than or equal to -offset. For optimal performance, the number of returned messages is chosen by TDLib and can be smaller than the specified limit.
bool	only_local_
	Pass true to get only messages that are available without sending network requests.

Static Public Attributes
static const std::int32_t	ID = -799960451
	Identifier uniquely determining a type of the object.

Detailed Description

Returns messages in a chat. The messages are returned in a reverse chronological order (i.e., in order of decreasing message_id). For optimal performance, the number of returned messages is chosen by TDLib. This is an offline request if only_local is true.

Returns object_ptr<Messages>.
