UName

Get information on hardware platform and operating system agent is running on.

Strings that are returned by uname functions are statically allocated in
libhostinfo, no need to dispose them

These functions are optional, and may return generic data is they are not
implemented on target platform

Linux

Linux shares implementation with POSIX, but provides domain name from uname() output.

hi_get_os_name() is redefined because uname() provides only a Linux Kernel name.
It collects information from following sources:

• /etc/oracle-release for Oracle Enterprise Linux
  
• /etc/redhat-release for RHEL other derivatives
  
• /etc/SuSE-release for SuSE derivatives
  
• lsb_release output for any other Linux
  

It also cuts out irrelevant words i.e. CentOS release 6.3 (Final) -> CentOS 6.3

hi_get_sys_name() provides information from /sys/class/dmi/id/ for x86 platforms
for non-x86 platforms, it'll probably return "Unknown system" string

POSIX

These functions are simple wrappers around uname() system call.
Getting hardware platform name and DNS domain name is not supported

Solaris

On Solaris hi_get_os_name() / hi_get_os_release() are based on /etc/release

First line of release file looks like:

<lot of spaces> <name of Solaris> <Version fields> <KernelID> [SPARC|X86] <misc. info>

Uses SPARC|X86 as an anchor to provide Kernel ID as OS release and rest of /etc/release's
first line as osname. Misc info is ignored

hi_get_sys_name() is implemented only for x86 using libsmbios

Windows

Uses GetVersionEx() and GetSystemInfo() pair of calls to get all system information
GetComputerName*() functions provide host name and domain

NOTE: Operating system name is deduced from dwMajorVersion / dwMinorVersion
so for newer Windows versions it may return "Unknown ..."
