如何在Android本机代码中使用共享内存? [英] How to use shared memory in android native code?

问题描述

我正在将现有的Linux应用程序移植到android.该应用程序正在使用诸如shm_open()等的共享内存API.

I am porting an existing linux application to android. The application is using shared memory API's like shm_open() etc.

检查

Checking bionic in android source, I see that these API's are not supported. Hence I get a linking error during build.

external/l2/avbtp.c:138: error: undefined reference to 'shm_open'
external/l2/avbtp.c:151: error: undefined reference to 'shm_unlink'
external/l2/avbtp.c:186: error: undefined reference to 'shm_unlink'

如何正确解决此问题?

推荐答案

Android intentionally doesn't provide SysV IPC. Try to avoid using of shared memory or, if you really want, look for examples of using ashmem.
