Function Documentation

void EXPORTED_PUBLIC _assert	(	bool	b,
		const char *	file,
		int	line,
		const char *	func
	)

Internal use only, the assert() macro passes the additional arguments automatically

void EXPORTED_PUBLIC panic

(

const char *

msg

)

Prints out a message to the screen and the most recent log entries and halts the processor. This function should only be called in unrecoverable emergency cases, e.g. when the kernel is unable to successfully complete its initialisation.

Note

This function and all functions called from this function may not allocate any resources, e.g. no I/O port & memory-region allocations and even no 'normal' memory allocations.

Parameters

[in]

msg

the message to print to the screen
