This method retrieves the ITypeCompinterface for the type description, which enables a client compiler to bind to the type description's members.

Syntax 

HRESULT GetTypeComp( 
  ITypeComp FAR* FAR* 
ppTComp 
);

Parameters

ppTComp

[out] Pointer to a pointer to the ITypeCompinstance for this ITypeLib. A client compiler uses the methods in the ITypeCompinterface to bind to types in ITypeLib, as well as to the global functions, variables, and constants defined in ITypeLib.

Return Value

The following table shows the return values for this function.

Value Description

S_OK

Success.

E_OUTOFMEMORY

Out of memory.

E_INVALIDARG

One or more of the parameters is invalid.

TYPE_E_IOERROR

The function could not read from the file.

TYPE_E_INVDATAREAD

Invalid data.

TYPE_E_UNSUPFORMAT

The type library has an older format.

TYPE_E_INVALIDSTATE

The type library could not be opened.

TYPE_E_WRONGTYPEKIND

Type mismatch.

Remarks

The ITypeComp::Bindfunction of the returned TypeCompbinds to global functions, variables, constants, enumerated values, and coclass members.

The Bindfunction also binds the names of the TYPEKINDenumerations of TKIND_MODULE, TKIND_ENUM, and TKIND_COCLASS. These names shadow any global names defined within the type information.

The members of TKIND_ENUM, TKIND_MODULE, and TKIND_COCLASS types marked as Application objects can be directly bound to from ITypeCompwithout specifying the name of the module.

Bindand ITypeComp::BindTypeaccept only unqualified names. ITypeLib::GetTypeCompreturns a pointer to the ITypeCompinterface, which is then used to bind to global elements in the library.

The names of some types (TKIND_ENUM, TKIND_MODULE, and TKIND_COCLASS) share the name space with variables, functions, constants, and enumerators.

If a member requires qualification to differentiate it from other items in the name space, GetTypeCompcan be called successively for each qualifier to bind to the member. This allows programming language compilers to access members of modules, enumerations, and coclasses, even though the member cannot be bound to with a qualified name.

Requirements

Header oaidl.h, oaidl.idl
Library oleaut32.lib, uuid.lib
