The truss utility executes the specified command and pro-
duces a trace of the system calls it performs, the signals
it receives, and the machine faults it incurs. Each line
of the trace output reports either the fault or signal
name or the system call name with its arguments and return
value(s).
System call arguments are displayed symbolically when
possible using defines from relevant system headers; for
any path name pointer argument, the pointed to string is
displayed.

Note: truss is basically for tracing system calls
