Introduction

The truss utility executes the specified command and produces 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. Error returns are reported using the error code names described in intro.
