Thanks Erik.
However I don't know how to truss running process.
Kenji Arisawa
for example:
; cat > truss.c
#include <u.h>
#include <libc.h>
void
main(void)
{
for(;;)
sleep(10*1000);
}
; 8c -FVTw truss.c && 8l -o truss truss.8
; truss&
; acid -l/sys/lib/acid/truss $apid
/proc/116801/text:386 plan 9 executable
/sys/lib/acid/port
/sys/lib/acid/386
/sys/lib/acid/truss
acid: truss()
sleep(10000)
return value: 0
