getChatHistory Class Reference

Inherits Function.

Description

Returns messages in a chat. The messages are returned in 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>.

Public Fields
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 message 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.

Public Types
using	ReturnType = object_ptr< messages >
	Typedef for the type returned by the function.

getChatHistory	(	int53	chat_id_,
		int53	from_message_id_,
		int32	offset_,
		int32	limit_,
		bool	only_local_
	)

Creates a function, which returns messages in a chat. The messages are returned in 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>.

Parameters
