Sh DESCRIPTION
The
Nm
Lua binding provides access to general kernel functionality like printing
messages on the console.
The
Em systm.aprint
functions are meant to be using during kernel autoconfiguration.
Pp
Bl -tag -width XXXX -compact
It Dv systm.print(msg)
Send
Ar msg
to the console.
Pp
It Dv systm.print_nolog(msg)
The
Fn systm.print_nolog
function is identical to the
Fn systm.print
function,
except is does not send
Ar msg
to the system log.
Pp
It Dv systm.uprint(msg)
Send
Ar msg
to the current process's controlling tty.
Pp
It Dv systm.aprint_normal(msg)
Send
Ar msg
to the console unless AB_QUIET is set.
Always sends to the log.
Pp
It Dv systm.aprint_naive(msg)
Send
Ar msg
to the console only if AB_QUIET is set.
Never sends to the log.
Pp
It Dv systm.aprint_verbose(msg)
Send
Ar msg
to the console only if AB_VERBOSE is set.
Always sends to the log.
Pp
It Dv systm.aprint_debug(msg)
Send
Ar msg
to the console and the log only if AB_DEBUG is set.
Pp
It Dv systm.aprint_error(msg)
Like
Fn systm.aprint_normal ,
but also keeps track of the number of times called.
This allows a subsystem to report the number of errors that occurred during a
quiet or silent initialization phase.
Pp
It Dv count = systm.aprint_get_error_count()
The
Fn systm.aprint_get_error_count
function reports the number of errors and
resets the counter to 0.
Pp
It Dv systm.panic(msg)
The
Fn systm.panic
function terminates the
Nx
system.
The message
Ar msg
is printed to the console and saved in the variable
Em panicstr
for later retrieval via core dump inspection.
A newline character is added at the end automatically.
El
Sh VARIABLES
Upon initialisation, the
Nm
module sets the following variables with the values of the corresponding kernel
variable:
Pp
Bl -tag -width XXXX -compact
It Dv systm.copyright
It Dv systm.cpu_model
It Dv systm.machine
It Dv systm.machine_arch
It Dv systm.osrelease
It Dv systm.ostype
It Dv systm.kernel_ident
It Dv systm.version
It Dv systm.ncpu
