I am porting an existing linux application to android. The application is using shared memory API's like
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'
Well, I found this github project and well it works! https://github.com/pelya/android-shmem
Like a magic, it works perfectly. You can use shared memory in android across independent processes using shmget(), shmat() and shmdt() API's seamlessly. Give it a try.
