Strace Linux System Call
 

Hello to all, how strace system call is really helpful in debugging ?

Thanks.

Strace is not a system call, but rather a program which prints out all the system calls made by program you are debugging (this notifies you of the arguments, return values, errors, etc. obtained from the system calls).

A similar program called ltrace will print out all (or selected) shared library calls (e.g., libc) made by your running program.

Thanks.
