uname(2)			 System	Calls			      uname(2)

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 operat-
       ing system in the structure pointed to by name.

       The uname() function uses the utsname structure,	 defined  in  <sys/ut-
       sname.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. Similarly,
       the nodename member contains the	name by	which the system is known on a
       communications network.	The release and	version	members	further	 iden-
       tify  the operating system. The machine member contains a standard name
       that identifies the hardware on which the operating system is running.

RETURN VALUES
       Upon successful completion, a non-negative value	 is  returned.	Other-
       wise, -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.
