Detailed Description

Globally unique identifier structure.

128 bit value that's generated in a specific way to give a reasonable assurance that the value is unique in the whole world. While it's not 100% perfect, it's the value system used by many subsystems for Windows.

Examples of GUIDs

GUID IID_IDirect3DTexture =
 {0x2CDCD9E0,0x25A0,0x11CF,{0xA3,0x1A,0x00,0xAA,0x00,0xB9,0x33,0x56 } };
GUID IID_IDirect3D =
 {0x3BBA0080,0x2421,0x11CF,{0xA3,0x1A,0x00,0xAA,0x00,0xB9,0x33,0x56 } };
