library attribute
The library statement contains all the information that the MIDL compiler uses to generate a type library.
[
uuid(uuid-number),
[, optional-attribute-list]
]
library library-name
{
library-definition-statements
}
Parameters
-
uuid-number
-
Specifies a universally unique identification number for the library.
-
optional-attribute-list
-
Specifies additional attributes that apply to the entire library statement. Allowable attributes include [control], [helpcontext], [helpfile], [helpstring], [hidden], [lcid], [restricted], and [version].
-
library-name
-
The name by which software components refer to the library.
-
library-definition-statements
-
One or more MIDL statements which define the contents of the library.
Remarks
Statements inside the library block can use elements that are declared inside or outside of the library block. Library statements can use those elements as base types, inheriting from those elements, or by simply referencing them on a line, as follows:
interface MyFace
{
// Interface definition statements
};
[
// library attributes
]
library
{
interface MyFace;
// Other library definition statements.
};
The MIDL compiler will create a type library that includes definitions for every element inside the library block, plus definitions for any elements defined outside and referenced from within the library block.
For information on generating both a type library and proxy stubs and headers from a single IDL file see Generating a Proxy DLL and a Type Library From a Single IDL File.
