Android memory dump

1.读取指定pid和内存地址的字符：

#include <stdlib.h>
#include <stdio.h>
#include <string.h>
#include <sys/ptrace.h>
#include <errno.h>
#include <dirent.h>

int pid = 17919;
long int addr = 0x12CBC270;

int main(int argc, void **argv)
{
    int ret = 0;
    char data = 0;

    printf("start...
");

    ret = ptrace(PTRACE_ATTACH, pid, 0, 0);

    if(ret == -1)
    {
        printf("ptrace fail,exit
");
        return 1;
    }

    waitpid(pid, NULL, 0);

    data = ptrace(PTRACE_PEEKDATA, pid, addr, NULL);

    printf("addr:%08lX data:%02X
",addr,data);

    ptrace(PTRACE_DETACH, pid, NULL, NULL);  

    return 0;
}
