propidl.h header

This header is used by multiple technologies. For more information, see:

• Structured Storage
• The Windows Shell
• Windows Property System

propidl.h contains the following programming interfaces:

Interfaces

IEnumSTATPROPSETSTG The IEnumSTATPROPSETSTG interface iterates through an array of STATPROPSETSTG structures containing statistical data about the property sets managed by the current IPropertySetStorage instance.
IEnumSTATPROPSTG The IEnumSTATPROPSTG interface iterates through an array of STATPROPSTG structures. The STATPROPSTG structures contain statistical data about properties in a property set.
IPropertySetStorage The IPropertySetStorage interface creates, opens, deletes, and enumerates property set storages that support instances of the IPropertyStorage interface.
IPropertyStorage The IPropertyStorage interface manages the persistent properties of a single property set. (IPropertyStorage interface)

Functions

FreePropVariantArray Frees the memory and references used by an array of PROPVARIANT structures.
PropVariantClear Clears a PROPVARIANT structure.
PropVariantCopy Creates a copy of a PROPVARIANT structure.
PropVariantInit The PropVariantInit function initializes a PROPVARIANT structure.Note  This function is implemented as a macro, available by including the provided ole2.h header file.
StgConvertPropertyToVariant Converts a SERIALIZEDPROPERTYVALUE data type to a PROPVARIANT data type.
StgConvertVariantToProperty Converts a PROPVARIANT data type to a SERIALIZEDPROPERTYVALUE data type.

Structures

PROPSPEC The PROPSPEC structure is used by many of the methods of IPropertyStorage to specify a property either by its property identifier (ID) or the associated string name.
PROPVARIANT The PROPVARIANT structure is used in the ReadMultiple and WriteMultiple methods of IPropertyStorage to define the type tag and the value of a property in a property set.
SERIALIZEDPROPERTYVALUE A range of memory of arbitrary type that represents a serialized PROPVARIANT structure.
STATPROPSETSTG The STATPROPSETSTG structure contains information about a property set. (STATPROPSETSTG structure)
STATPROPSTG The STATPROPSTG structure contains data about a single property in a property set. This data is the property ID and type tag, and the optional string name that may be associated with the property.
