The PROP_ID macro returns the property identifier of a specified property tag.


PROP_ID (ulPropTag)


  • ulPropTag
    Property tag containing the identifier to be returned.


Every property tag contains the property type in the low-order word (bits 0 through 15) and the property identifier in the high-order word (bits 16 through 31). The PROP_ID macro extracts the property identifier and places it in bits 0 through 15 of the integer to be returned. The remaining bits of the return value are set to zeros.
