Shared Memory File System
|
|
=========================
|
|
|
|
This supports the POSIX shm_open() APIs for shared memory among unrelated
|
|
apps.
|
|
|
|
It can be enabled with ``CONFIG_FS_SHMFS=y``. To check how it works, please
|
|
also enable the example app via ``CONFIG_EXMAPLE_SHM=y`` and run ``shm_test``
|
|
from NSH command line.
|
|
|
|
This file system doesn't support mount operations though.
|
|
|
|
If comment the line using ``shm_unlink()`` in the example app, we can see
|
|
a file under ``/var/shm/`` from NSH command line after running the example.
|
|
We can also remove that file from command line.
