| .. zephyr:code-sample:: posix-uname |
| :name: uname() |
| |
| Use ``uname()`` to acquire system information and output it to the console. |
| |
| Overview |
| ******** |
| |
| In this sample application, the POSIX `uname()`_ function is used to acquire system information and |
| it is output to the console. Additionally, uname is added as a shell command and system information |
| is displayed according to the option(s) provided for the command. |
| |
| Building and Running |
| ******************** |
| |
| This project outputs to the console. It can be built and executed on QEMU as follows: |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/posix/uname |
| :host-os: unix |
| :board: qemu_x86 |
| :goals: run |
| :compact: |
| |
| For comparison, to build directly for your host OS if it is POSIX compliant (for ex. Linux): |
| |
| .. code-block:: console |
| |
| cd samples/posix/uname |
| make -f Makefile.host |
| |
| The make output file will be located in samples/posix/uname/build. |
