WIFEXITED(stat_val) Evaluates to a non-zero value if statuswas returned for a child process thatterminated TATUS(stat_val) If the value of WIFEXITED(stat_val) isnon-zero, this macro evaluates to thelow-order 8 bits of the status argumentthat the child process passed to _exit()or exit(), or the value the childprocess returned from main().
