The GUID structure describes a globally unique identifier.

Syntax

struct { 
  unsigned long Data1; 
  unsigned short Data2; 
  unsigned short Data3; 
  unsigned char Data4[8]; 
} GUID;

Members

  • Data1
    An unsigned long integer data value.
  • Data2
    An unsigned short integer data value.
  • Data3
    An unsigned short integer data value.
  • Data4
    An array of unsigned characters.

Remarks

GUID structures are used in MAPI as follows:

  • In the MAPIUID structures that uniquely identify service providers.
  • For interface identifiers.
  • In the property set names of named properties.

Message store and address book providers call the Microsoft utility UUIDGEN.EXE to generate a GUID structure to use in their MAPIUID structure.
