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.

	   nodename	 Network name of this machine.

	   release	 Release level of the operating system.

	   version	 Version level of the operating system.

	   machine	 Machine hardware platform.

RETURN VALUES

     The uname() function returns the value 0 if successful; otherwise the value -1 is returned and the global variable errno is set to indicate
     the error.

ERRORS

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

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 fur-
       ther  identify 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. 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.
