常将有日思无日，莫把无时当有时-
堆是堆，栈是栈
// 一位工程师写的示例代码 // 向这位工程师致敬！ // int a = 0; //全局初始化区 int a = 0; //全局初始化区 char *p1; //全局未初始化区 main() { int b; //栈 char s[] = "abc"; //栈 char *p2; //栈 char *p3 = "123456"; //123456\0在常量区，p3在栈上。 static int c = 0; //全局（静态）初始化区 p1 = (char *)malloc(10); p2 = (char *)malloc(20); //分配得来得10和20字节的区域就在堆区。 strcpy(p1, "123456"); //123456\0放在常量区，编译器可能会将它与p3所指向的"123456"优化成一个地方。 }

android利用adb传输文件
准备条件：
1 板子通过usb2uart连接到ubuntu虚拟机（可移动设备名称为：Google Salxxxxxx）。
并启动android。
2 虚拟机上首先要安装VMware Tools（否则，会看不到共享文件夹）。
3 启用windows下共享文件夹、
(1)要传输的文件，例如，test.txt
(2)android img文件夹——含adb命令
以上两者均位于该共享文件夹。
操作：
1 虚拟机上，进入终端，并进入上述共享文件夹下，或软连接目录。
2 shell下，
$ ./adb root restarting adbd as root $ ./adb shell （可以进入板上目录） salvator:/ # ls acct dev init.zygote64_32.rc sdcard bin etc lost+found storage bugreports init mnt sys cache init.environ.rc odm system charger init.rc oem ueventd.rc config init.recovery.salvator.rc postinstall vendor d init.usb.configfs.rc proc data init.usb.rc product default.prop init.zygote32.rc sbin salvator:/sdcard/Movies # exit $ ./adb push /home/titron/test.txt /sdcard/Download $ ./adb push /home/m3n_imgs/aaa.mp3 /data/media/0/Download $ ./adb push /home/m3n_imgs/bbb.apk /data/media/0/Download # 说明： # 推送到/data/media/0/Download， # 相当于推送到/sdcard/Download # # "/data/media/0"是安卓手机内置存储的真实目录， # 而"/sdcard"是内置存储被安卓系统挂载的快捷方式（指向"/data/media/0"）； # 通常需要存储空间权限的手机app会访问后者，前者需要ROOT权限才能访问，因此这两个文件夹是一个目录 # 有关android内部存储和外部存储，请参看下面的附录连接。附录：
