示例#1

文件： main.c 项目： smillaedler/rr

	int aslr_val =
		read_int_file("/proc/sys/kernel/randomize_va_space");
	int ptrace_scope_val =
		read_int_file("/proc/sys/kernel/yama/ptrace_scope");
	if (aslr_val != 0) {
		fatal("ASLR not disabled; randomize is %d", aslr_val);
	}
	if (ptrace_scope_val > 0) {
		fatal("Can't write to process memory; ptrace_scope is %d",
