entry attribute

The [entry] attribute specifies an exported function or constant in a module by identifying the entry point in the DLL.

[
    uuid(uuid-number), 
    entry(entry-id)
  [, optional-attribute-list]
]
module modulename 
{
    elementlist
};

Parameters

uuid-number

Specifies a universally unique identification number for the module.

entry-id

Specifies the module entry point function name or integer identification number.

optional-attribute-list

Specifies zero or more attributes for the MIDL compiler to apply to the module.

modulename

Specifies the name other software components use to denote the module.

elementlist

Specifies one or more module element definition statements.

Remarks

If the entryid variable of the [entry] attribute is a string, this is a named entry point. If entryid is a number, the entry point is defined by an ordinal. This attribute provides a way to obtain the address of a function in a module.

Examples

[
    dllname("MyAppsFirst.dll")
] 
module MyModule
{
    [entry(20), bindable, requestedit, 
     propputref, defaultbind ] HRESULT Func1(
         [in]IUnknown * Param1, 
         [out] MyType * Param2);
    [entry("TwentyOne"), hidden, vararg] SAFEARRAY (int) Func2(
        [in, out] SAFEARRAY (variant) *varP) ;
    [entry(22)] Float Func3(
        [in] lpstr pName, [in] double dLevel,
        [out] short * sByte) ;
    } ;
