◆ AppendStringToHistory()

EFI_STATUS AppendStringToHistory	(	IN CONST CHAR16 *	String,
		IN CONSOLE_LOGGER_PRIVATE_DATA *	ConsoleInfo
	)

Appends a string to the history buffer. If the buffer is full then the oldest information in the buffer will be dropped. Information is added in a line by line manner such that an empty line takes up just as much space as a full line.

Parameters

[in]	String	String pointer to add.
[in]	ConsoleInfo	The pointer to the instance of the console logger information.

Definition at line 460 of file ConsoleLogger.c.

◆ ConsoleLoggerClearScreen()
