Types

type BIOSInfo

type BIOSInfo struct {
	Vendor      string
	Version     string
	BiosVersion string
	ReleaseDate string
}

type BIOSInfoRead

type BIOSInfoRead struct {
	Vendor      byte
	Version     byte
	StartAddSeg uint16
	ReleaseDate byte
}

type BaseboardInfo

type BaseboardInfo struct {
	Manufacturer string
	Product      string
	Version      string
	SerialNumber string
}

type Decoder

type Decoder struct {
	Version SMBIOSVersion
	// contains filtered or unexported fields
}

A Decoder decodes Structures from a stream.

func NewDecoder

func NewDecoder(r io.Reader) *Decoder

NewDecoder creates a Decoder which decodes Structures from the input stream.

func (*Decoder) Decode

func (d *Decoder) Decode() ([]*Structure, error)

Decode decodes Structures from the Decoder's stream until an End-of-table structure is found.

type EntryPoint

type EntryPoint interface {
	// Table returns the memory address and maximum size of the SMBIOS table.
	Table() (address, size int)

	// Version returns the system's SMBIOS version.
	Version() (major, minor, revision int)
}

An EntryPoint is an SMBIOS entry point. EntryPoints contain various properties about SMBIOS.

Use a type assertion to access detailed EntryPoint information.

func ParseEntryPoint

func ParseEntryPoint(r io.Reader) (EntryPoint, error)

ParseEntryPoint parses an EntryPoint from the input stream.

func Stream

func Stream() (io.ReadCloser, EntryPoint, error)

Stream locates and opens a stream of SMBIOS data and the SMBIOS entry point from an operating system-specific location. The stream must be closed after decoding to free its resources.

If no suitable location is found, an error is returned.
