uname(2)
NAME
  uname - Gets the name of the current system

SYNOPSIS
  #include <sys/utsname.h>

  int uname(
	  struct utsname *name);

STANDARDS
  Interfaces documented on this reference page conform to industry standards
  as follows:

  uname():  XPG4, XPG4-UNIX

  Refer to the standards(5) reference page for more information about
  industry standards and associated tags.

PARAMETERS
  name	    Points to a utsname structure.

DESCRIPTION
  The uname() function stores information identifying the current system in
  the structure pointed to by the name parameter.

  The uname() function uses the utsname structure, which is defined in the
  sys/utsname.h file and contains the following members:
       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 system in the sysname character array. The nodename array contains
  the name that the system is known by on a communications network. The
  release and version arrays further identify the system. The machine array
  identifies the CPU hardware being used.

RETURN VALUES
  Upon successful completion, a nonnegative value is returned.	Otherwise, -1
  is returned and errno is set to indicate the error.

ERRORS
  If the uname() function fails, errno may be set to the following value:

  [EFAULT]  [Digital]  The name parameter points outside of the process
	    address space.
