uname - get basic data on current operating system

Syntax

#include <sys/utsname.h> int uname(struct utsname *name);

Description uname() obtains basic information on the current operating system and stores it in the

	structure pointed to by name. uname() uses the utsname structure defined in sys/utsname.h. The members of the structure are the char arrays sysname, nodename, release, version and machine. The name of the current operating system is entered in the array sysname. Similarly, nodename contains the name that the system is known by on a communications network. The arrays release and version contain the release number and release date of the operating system, and the array machine contains a name that identifies the hardware on which the system is running.
Return val.	Non-negative value
		if successful.
	-1	if an error occurs. errno is set to indicate the error.
Errors	uname() will fail if: Extension EFAULT     name is an invalid address. (End)
Notes	The inclusion of the nodename member in this structure does not mean that this information is sufficient for addressing communications networks.
