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.
