GetIsInteractive()

bool IOHandler::GetIsInteractive

(

)

Check if the input is being supplied interactively by a user.

This will return true if the input stream is a terminal (tty or pty) and can cause IO handlers to do different things (like for a confirmation when deleting all breakpoints).

GetIsRealTerminal()

bool IOHandler::GetIsRealTerminal

(

)

Check if the input is coming from a real terminal.

A real terminal has a valid size with a certain number of rows and columns. If this function returns true, then terminal escape sequences are expected to work (cursor movement escape sequences, clearing lines, etc).
