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>:

struct utsname {
charsysname[9];
charnodename[9];
charrelease[9];
charversion[9];
};
extern struct utsname utsname;

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. 

Uname will fail if name points to an invalid address.  ­[EFAULT]

RETURN VALUE

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