NAME
     uname - get system identification

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <sys/utsname.h>

     int
     uname(struct utsname *name);

DESCRIPTION
     The uname() function stores nul-terminated strings of information
     identifying the current system into the structure referenced by name.

     The utsname structure is defined in the <sys/utsname.h> header file, and
     contains the following members:

           sysname       Name of the operating system implementation.
                         Equivalent to the sysctl(7) kern.ostype variable.

           nodename      Network name of this machine.  Equivalent to the
                         sysctl(7) kern.hostname variable.

           release       Release level of the operating system.  Equivalent to
                         the sysctl(7) kern.osrelease variable.

           version       Version level of the operating system.  Equivalent to
                         the sysctl(7) kern.version variable, except that very
                         long values are truncated, and newlines are converted
                         to spaces.

           machine       Machine hardware platform.  Equivalent to the
                         sysctl(7) hw.machine variable.

RETURN VALUES
     If uname is successful, 0 is returned, otherwise, -1 is returned and
     errno is set appropriately.

ERRORS
     The uname() function may fail and set errno for any of the errors
     specified for the library functions sysctl(3).
