Syntax
HRESULT GetFuncDesc( unsigned int index,
FUNCDESC FAR* FAR* ppFuncDesc );
Parameters
index
Index of the function whose description is to be returned. The index should be in the range of 0 to 1 less than the number of functions in this type.
ppFuncDesc
On return, pointer to a pointer to a FUNCDESC that describes the specified function.

One of the values described in the following table is returned.
Value | Description |
S_OK | Success. |
E_OUTOFMEMORY | Out of memory. |
E_INVALIDARG | One or more of the parameters is invalid. |

TYPE_E_UNSUPFORMAT | The type library has an older format. |
TYPE_E_INVALIDSTATE | The type library could not be opened. |
Remarks
The function GetFuncDesc provides access to a FUNCDESC structure that describes the function with the specified index. The FUNCDESC should be freed with ITypeInfo::ReleaseFuncDesc. The number of functions in the type is one of the attributes contained in the TYPEATTR structure.
Example
CHECKRESULT(ptypeinfo->GetFuncDesc(i, &pfuncdesc));
idMember = pfuncdesc->elemdescFunc.ID;
CHECKRESULT(ptypeinfo->GetDocumentation(idMember, &bstrName, NULL, NULL, NULL));
ptypeinfo->ReleaseFuncDesc(pfuncdesc);
