FILE *srcFile = fopen(binaryPath, "r");
        if (srcFile == NULL)
        {
            int errNum = 0;
            errNum = errno;
            printf("open fail errno = %d reason = %s \n", errNum, strerror(errNum));
            fprintf(stderr, "Error: Could not open binary %s\n", binaryPath);
            exit(1);
