ExpansionFunction.GetFunctionType(UInt32) Method

Definition

Gets the type of the function; that is, what type of value the function returns.

public:
 virtual int GetFunctionType([Runtime::InteropServices::Out] System::UInt32 % pFuncType);
 virtual int GetFunctionType([Runtime::InteropServices::Out] unsigned int & pFuncType);
public virtual int GetFunctionType (out uint pFuncType);
abstract member GetFunctionType : uint32 -> int
override this.GetFunctionType : uint32 -> int
Public Overridable Function GetFunctionType (ByRef pFuncType As UInteger) As Integer

Parameters

pFuncType
UInt32

[out] A value from the _ExpansionFunctionType enumeration specifying the type of the expansion function.

Returns

If successful, returns S_OK; otherwise, returns an error code.

Implements

Remarks

This method determines what is returned from the expansion function: a value or a list. If the expansion function returns a value, then the GetCurrentValue(String, Int32) method is called to obtain that value. If the expansion function returns a list, then the GetListText method is called to obtain a value from the list.

This method is an implementation of the GetFunctionType method on the IVsExpansionFunction interface.

The base method returns eft_Value if the expansion function returns a single value or eft_List if the expansion function returns a list of values. The base method always returns a success code of S_OK.
