uname()

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:

west build -b qemu_x86 samples/posix/uname
west build -t run

For comparison, to build directly for your host OS if it is POSIX compliant (for ex. Linux):

cd samples/posix/uname
make -f Makefile.host

The make output file will be located in samples/posix/uname/build.
