aulPropTag

Array of property tags.

A property tag is a 32-bit unsigned integer that consists of two parts:

  • An identifier in the high-order 16 bits.

  • A type in the low-order 16 bits.

The identifier is a numeric value in a particular range. MAPI defines ranges for identifiers to describe what the property is used for and who is responsible for maintaining it. MAPI defines constraints for each of the property tags that it supports in the Mapitags.h header file.

The type indicates the format for the property's value. MAPI defines constants for each of the property types that it supports in the Mapidefs.h header file.

For more information about property tags and their components, see one of the following topics:
