Equivalent to the sysctl(7) kern.osrelease variable. version Version level of the operating system. Equivalent to the sysctl(7) kern.version variable, except that very long values are truncated, and newlines are converted to spaces. machine Machine hardware platform. Equivalent to the sysctl(7) hw.machine variable.
If uname is successful, 0 is returned, otherwise, -1 is returned and errno is set appropriately.
