Explain why setting the name of the successor process using `argv[0]` in `execl()` might not reflect correctly at the OS level. How can this be correctly achieved?
Setting the name of the successor process might not reflect correctly as if we are giving a relative path in the API call, the system may not be able to find it. This can be correctly achieved by specifying the appropriate path. This can be corrected using the prctl API or pthread_setname_np pthreads API. It could be used as prctl(PR_SET_NAME,argv[2],0,0)
