Re: [Valgrind-users] Difference between "truss" and "valgrind --trace-syscalls=yes" on FreeBSD

[Yue C. <yc...@gm...>]

I mean the result from

"valgrind --trace-syscalls=yes ./myprogram"   VS   "truss ./myprogram"
are different;

NOT
"truss valgrind --trace-syscalls=yes ./program"  VS  "truss ./program".

Can I modify some Valgrind source code to mark the syscalls issued from
Valgrind itself?
