pub fn println(ctx: &ServiceContext, s: &str)Expand description
Write a line to the console.
A line of any length is written whole, in pieces of at most 256 bytes. It may park the caller
briefly: serial output is synchronous, and when the console service’s queue is full the kernel
parks the writer until there is room (handle_console_write). A program printing in a tight loop
runs at the speed of the screen. Authority: log_write.
