ITypeLib::GetTypeComp method (oaidl.h)
Enables a client compiler to bind to the types, variables, constants, and global functions for a library.
Syntax
HRESULT GetTypeComp(
[out] ITypeComp **ppTComp
);
Parameters
[out] ppTComp
The ITypeComp instance for this ITypeLib. A client compiler uses the methods in the ITypeComp interface to bind to types in ITypeLib, as well as to the global functions, variables, and constants defined in ITypeLib
Return value
This method can return one of these values.
| Return code | Description |
|---|---|
|
Success. |
|
One or more of the arguments is not valid. |
|
Insufficient memory to complete the operation. |
Remarks
The Bind function of the returned TypeComp binds to global functions, variables, constants, enumerated values, and coclass members. The Bind function also binds the names of the TYPEKIND enumerations 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 ITypeComp without specifying the name of the module.
ITypeComp::Bind and ITypeComp::BindType accept only unqualified names. ITypeLib::GetTypeComp returns a pointer to the ITypeComp interface, 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, GetTypeComp can be called successively for each qualifier in order to bind to the desired member. This allows programming language compilers to access members of modules, enumerations, and coclasses, even though the member can't be bound to with a qualified name.
