+.SH PROLOG
+This manual page is part of the POSIX Programmer's Manual.
+The Linux implementation of this interface may differ (consult
+the corresponding Linux manual page for details of Linux behavior),
+or the interface may not be implemented on Linux.
+.SH NAME
+uname \- get the name of the current system
+.SH SYNOPSIS
+.LP
+\fB#include <sys/utsname.h>
+.br
+.sp
+int uname(struct utsname *\fP\fIname\fP\fB);
+.br
+\fP
+.SH DESCRIPTION
+.LP
+The \fIuname\fP() function shall store information identifying the
+current system in the structure pointed to by
+\fIname\fP.
+.LP
+The \fIuname\fP() function uses the \fButsname\fP structure defined
+in \fI<sys/utsname.h>\fP.
+.LP
+The \fIuname\fP() function shall return a string naming the current
+system in the character array \fIsysname\fP. Similarly,
+\fInodename\fP shall contain the name of this node within an implementation-defined
+communications network. The arrays
+\fIrelease\fP and \fIversion\fP shall further identify the operating
+system. The array \fImachine\fP shall contain a name that
+identifies the hardware that the system is running on.
+.LP
+The format of each member is implementation-defined.
+.SH RETURN VALUE
+.LP
+Upon successful completion, a non-negative value shall be returned.
+Otherwise, -1 shall be returned and \fIerrno\fP set to
+indicate the error.
+.SH ERRORS
+.LP
+No errors are defined.
+.LP
+\fIThe following sections are informative.\fP
+.SH EXAMPLES
+.LP
+None.
+.SH APPLICATION USAGE
+.LP
+The inclusion of the \fInodename\fP member in this structure does
+not imply that it is sufficient information for interfacing
+to communications networks.
+.SH RATIONALE
+.LP
+The values of the structure members are not constrained to have any
+relation to the version of this volume of
+IEEE\ Std\ 1003.1-2001 implemented in the operating system. An application
+should instead depend on _POSIX_VERSION and
+related constants defined in \fI<unistd.h>\fP.
+.LP
+This volume of IEEE\ Std\ 1003.1-2001 does not define the sizes of
+the members of the structure and permits them to be
+of different sizes, although most implementations define them all
+to be the same size: eight bytes plus one byte for the string
+terminator. That size for \fInodename\fP is not enough for use with
+many networks.
+.LP
+The \fIuname\fP() function originated in System III, System V, and
+related implementations, and it does not exist in Version 7
+or 4.3 BSD. The values it returns are set at system compile time in
+those historical implementations.
+.LP
+4.3 BSD has \fIgethostname\fP() and \fIgethostid\fP(), which return
+a symbolic name and a numeric value, respectively. There are
+related \fIsethostname\fP() and \fIsethostid\fP() functions that are
+used to set the values the other two functions return. The
+former functions are included in this specification, the latter are
+not.
+.SH FUTURE DIRECTIONS
+.LP
+None.
