uname − get name of current UNIX system

SYNOPSIS

#include <sys/utsname.h>

int uname(struct utsname ∗name);

DESCRIPTION

uname stores information identifying the current UNIX system in the structure pointed to by name. 

uname uses the structure utsname defined in sys/utsname.h whose members are:

charsysname[SYS_NMLN];
charnodename[SYS_NMLN];
charrelease[SYS_NMLN];
charversion[SYS_NMLN];
charmachine[SYS_NMLN];

uname returns a null-terminated character string naming the current UNIX system in the character array sysname.  Similarly, nodename contains the name that the system is known by on a communications network.  release and version further identify the operating system.  machine contains a standard name that identifies the hardware that the UNIX system is running on. 

EFAULT uname fails if name points to an invalid address.
