| ========================= |
| 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. |
