.Sh NAME
.Nm uname
.Nd get host information
.Sh SYNOPSIS
.Fd #include <sys/utsname.h>
.Ft int
.Fn uname "struct utsname *name"
.Sh DESCRIPTION
.Fn Uname
returns the information identifying the current UNIX system
in the structure pointed to by
.Fa name.
.Pp
.Fn Uname
uses the structure defined in
.Aq Pa sys/utsname.h
whose members are:
.Bd -literal
struct utsname {
char sysname[SYS_NMLN];
char nodename[SYS_NMLN];
char release[SYS_NMLN];
char version[SYS_NMLN];
char machine[SYS_NMLN];
};
.Ed
.Pp
.Fn Uname
returns a null-terminated character string naming the
current UNIX system in the character array
.Fa sysname .
Similarly,
.Fa nodename
contains the name that the system is known by on a
communication network.
.Fa Release
and
.Fa version
further identify the operating system.
.Fa Machine
contains the standard name that identifies the hardware
that the UNIX system is running on.
.Sn ERRORS
.Bl -tag -width ENAMETOOLONGAA
.It Bq Er EFAULT
.Fn Uname
will fail if
.Fa name
points to an invalid address.
.Sh RETURN VALUE
Upon successful completion a value of 0 is returned.
Otherwise, a value of -1 is returned and
.Va errno
is set to indicate the error.
.Sh SEE ALSO
.Xr hostname 1 ,
.Xr machine 1 ,
.Xr gethostname 2
.Sh HISTORY
The
.Nm uname
function call appeared in
System V.2 AT&T UNIX.
