posix_uname - Get system name

SYNOPSIS

       array posix_uname (void	)

DESCRIPTION

	Gets information about the system.

	Posix requires that assumptions must not be made about the format of the values, e.g. the assumption that a release may contain three dig-
       its or anything else returned by this function.

RETURN VALUES

	Returns a hash of strings with information about the system. The indices of the hash are

	      o sysname - operating system name (e.g. Linux)

	      o nodename - system name (e.g. valiant)

	      o release - operating system release (e.g. 2.2.10)

	      o version - operating system version (e.g. #4 Tue Jul 20 17:01:36 MEST 1999)

	      o machine - system architecture (e.g. i586)

	      o domainname - DNS domainname (e.g. example.com)

	domainname is a GNU extension and not part of POSIX.1, so this field is only available on GNU systems or when using the GNU libc.

EXAMPLES

       Example #1

	      Example use of posix_uname(3)

	      <?php
	      $uname=posix_uname();
	      print_r($uname);
	      ?>

	      The above example will output something similar to:

	      Array
	      (
		  [sysname] => Linux
		  [nodename] => funbox
		  [release] => 2.6.20-15-server
		  [version] => #2 SMP Sun Apr 15 07:41:34 UTC 2007
		  [machine] => i686
	      )

NAME

       uname - get name of current operating system

SYNOPSIS

       #include <sys/utsname.h>

       int uname(struct utsname *name);

DESCRIPTION

       The uname() function stores information identifying the current operating system in the structure pointed to by name.

       The uname() function uses the utsname structure, defined in <sys/utsname.h>, whose members include:

       char    sysname[SYS_NMLN];
       char    nodename[SYS_NMLN];
       char    release[SYS_NMLN];
       char    version[SYS_NMLN];
       char    machine[SYS_NMLN];

       The  uname()  function returns a null-terminated character string naming the current operating system in the character array sysname. Simi-
       larly, the nodename member contains the name by which the system is known on a communications network.  The  release  and  version  members
       further identify the operating system. The machine member contains a standard name that identifies the hardware on which the operating sys-
       tem is running.

RETURN VALUES

       Upon successful completion, a non-negative value is returned. Otherwise, -1 is returned and errno is set to indicate the error.

ERRORS

       The uname() function will fail if:

       EFAULT	       The name argument points to an illegal address.
