NAME

uname − get name of current UNIX system

SYNOPSIS

#include <sys/utsname.h>

int uname (name)
struct utsname ∗name;

DESCRIPTION

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

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

charsysname[9];
charnodename[9];
charrelease[9];
charversion[9];
charmachine[9];

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.

Upon successful completion, a non-negative value is returned.  Otherwise, a value of −1 is returned and errno is set to indicate the error.
