Interfaces Property

项目
09/21/2010

The Interfaces property gets the collection of SoftUSBInterface objects that represent the set of interfaces and their alternates that the configuration supports.

This property is read-only.

Syntax

HRESULT get_Interfaces(
  [out, retval]  ISoftUSBInterfaces **ppiInterfaces
);

Property Value

A pointer to caller-allocated space to hold the returned interface pointer to the collection of SoftUSBInterface objects. The caller must release this pointer.

Error Codes

Interfaces returns S_OK if the operation succeeds or E_POINTER if the ppiInterfaces parameter is not a valid pointer.

Remarks

The collection that is returned from the Interfaces property must be populated with a SoftUSBInterface object for each alternate of each interface that the configuration supports.

The following C++ code example shows how to get the Interfaces property.

HRESULT GetInterfaces
(
 ISoftUSBConfiguration  *piConfig,
 ISoftUSBInterfaces **ppiInterfaces
)
{
 return piConfig->get_Interfaces(ppiInterfaces);
}
