oaidl.h header
This header is used by Automation. For more information, see:
oaidl.h contains the following programming interfaces:
Interfaces
| ICreateErrorInfo Returns error information. |
| ICreateTypeInfo Provides the tools for creating and administering the type information defined through the type description. (ICreateTypeInfo) |
| ICreateTypeInfo2 Provides the tools for creating and administering the type information defined through the type description. (ICreateTypeInfo2) |
| ICreateTypeLib Provides the methods for creating and managing the component or file that contains type information. (ICreateTypeLib) |
| ICreateTypeLib2 Provides the methods for creating and managing the component or file that contains type information. (ICreateTypeLib2) |
| IDispatch Exposes objects, methods and properties to programming tools and other applications that support Automation. |
| IEnumVARIANT Provides a method for enumerating a collection of variants, including heterogeneous collections of objects and intrinsic types. |
| IErrorInfo Provides detailed contextual error information. |
| IErrorLog Communicates detailed error information between a client and an object. |
| IPropertyBag Provides an object with a property bag in which the object can save its properties persistently. |
| IRecordInfo Describes the structure of a particular UDT. |
| ISupportErrorInfo Ensures that error information can be propagated up the call chain correctly. Automation objects that use the error handling interfaces must implement ISupportErrorInfo. |
| ITypeChangeEvents Enables clients to subscribe to type change notifications on objects that implement the ITypeInfo, ITypeInfo2, ICreateTypeInfo, and ICreateTypeInfo2 interfaces. |
| ITypeComp The ITypeComp interface provides a fast way to access information that compilers need when binding to and instantiating structures and interfaces. |
| ITypeInfo Used for reading information about objects. (ITypeInfo) |
| ITypeInfo2 Used for reading information about objects. (ITypeInfo2) |
| ITypeLib Represents a type library, the data that describes a set of objects. (ITypeLib) |
| ITypeLib2 Represents a type library, the data that describes a set of objects. (ITypeLib2) |

| BSTR_UserMarshal Marshals a BSTR object into the RPC buffer. (BSTR_UserMarshal) |
| BSTR_UserMarshal64 Marshals a BSTR object into the RPC buffer. (BSTR_UserMarshal64) |

| BSTR_UserSize64 Calculates the wire size of the BSTR object, and gets its handle and data. (BSTR_UserSize64) |
| BSTR_UserUnmarshal Unmarshals a BSTR object from the RPC buffer. (BSTR_UserUnmarshal) |

| VARIANT_UserMarshal Marshals a VARIANT object into the RPC buffer. (VARIANT_UserMarshal) |
| VARIANT_UserMarshal64 Marshals a VARIANT object into the RPC buffer. (VARIANT_UserMarshal64) |
| VARIANT_UserSize Calculates the wire size of the VARIANT object, and gets its handle and data. (VARIANT_UserSize) |
| VARIANT_UserSize64 Calculates the wire size of the VARIANT object, and gets its handle and data. (VARIANT_UserSize64) |
| VARIANT_UserUnmarshal Unmarshals a VARIANT object from the RPC buffer. (VARIANT_UserUnmarshal) |
| VARIANT_UserUnmarshal64 Unmarshals a VARIANT object from the RPC buffer. (VARIANT_UserUnmarshal64) |
Structures
| ARRAYDESC Describes an array, its element type, and its dimension. |
| BINDPTR Describes a pointer. |
| CUSTDATA Represents custom data. |
| CUSTDATAITEM Represents a custom data item. |
| DISPPARAMS Contains the arguments passed to a method or property. |
| ELEMDESC The ELEMDESC structure contains the type description and process-transfer information for a variable, a function, or a function parameter. (ELEMDESC) |
| EXCEPINFO Describes an exception that occurred during IDispatch::Invoke. |
| FUNCDESC Describes a function. (FUNCDESC) |
| PARAMDESC Contains information needed for transferring a structure element, parameter, or function return value between processes. |
| PARAMDESCEX Contains information about the default value of a parameter. |
| SAFEARRAY Represents a safe array. |
| SAFEARRAYBOUND Represents the bounds of one dimension of the array. |
| TLIBATTR Contains information about a type library. Information from this structure is used to identify the type library and to provide national language support for member names. |
| TYPEATTR Contains attributes of a type. |
| TYPEDESC Describes the type of a variable, the return type of a function, or the type of a function parameter. |
| VARDESC Describes a variable, constant, or data member. |
| VARIANT VARIANTARG describes arguments passed within DISPPARAMS, and VARIANT to specify variant data that cannot be passed by reference. |
