register_console − take on kernel console duties

SYNOPSIS

extern void register_console(void(*proc)(const char*))

DESCRIPTION

This function registers with the kernel a function to display all the kernel messages printed by the printk(9) function.

This function is normally called once at boot time by the device driver for the console device, whatever that turns out to be for the machine. The console procedure is only called to print messages that are to be printed, the filtering for log level is done already.

BUGS

Only one console can exist at a time, and there is no way to know if any other device has registered as a console.
