PSEnumeratePropertyDescriptions function (propsys.h)

A wrapper API that calls the schema subsystem's IPropertySystem::EnumeratePropertyDescriptions. This function retrieves an instance of the subsystem object that implements IPropertyDescriptionList, to obtain either the entire list or a partial list of property descriptions in the system.

Syntax

PSSTDAPI PSEnumeratePropertyDescriptions(
  [in]  PROPDESC_ENUMFILTER filterOn,
  [in]  REFIID              riid,
  [out] void                **ppv
);

Parameters

[in] filterOn

Type: PROPDESC_ENUMFILTER

The list to return. PROPDESC_ENUMFILTER shows the valid values for this method.

[in] riid

Type: REFIID

Reference to the interface ID of the requested interface.

[out] ppv

Type: void**

The address of an IPropertyDescriptionList interface pointer.

Return value

Type: PSSTDAPI

Returns one of the following values.

Remarks

We recommend that you use the IID_PPV_ARGS macro, defined in objbase.h, to package the riid and ppv parameters. This macro provides the correct IID based on the interface pointed to by the value in ppv, eliminating the possibility of a coding error.
