Hi Manju,

 

Android uses the Bionic C library (under /bionic)... my understanding is that this is not fully POSIX compliant.

 

Android also has the Binder IPC mechanism (under /frameworks/base/libs/binder) which uses a Linux misc kernel driver (binder.c). The kernel driver is not in the AOSP source code itself, but available on the web.

 

Cheers,

 

Nigel

The different IPC mechanisms supported by android are

1. Intents

2. Ashmem [Anonymous SHared MEMory]

3. Binder IPC

Binder IPC is the custom IPC mechanism for android

As nigel said i don't think  IPC mechanisms are POSIX complaint.

I would add

4. kernel objects or communications via sysfs file handles

5. sockets

Good luck ! Frank
