OS/161 Reference Manual


ltrace - LAMEbus trace device


device ltrace* at lamebus*


ltrace is a driver for the LAMEbus trace and debug card. This device can be used to turn on and off System/161 tracing (with trace161); it can also be used to emit debug printouts with much lower latency than printing to the console. Finally, it can be used to cause a dump of the entire System/161 system state.

The calls for these operations are provided to the kernel via the header file <lamebus/ltrace.h>.

Only the first ltrace device found, if any, is actually used. If none is found, the calls have no effect.
