Embodiment Construction

[0014] The following paragraphs provide exemplary operating environments in which such an operating system may be implemented.

[0015] refer to figure 1 , the computer system 100 includes an operating system 102 that communicates with the computer hardware (see Figure 4 ) in combination to provide a platform on which various applications 104 run. Applications run as processes managed by the operating system that consume or otherwise have access to resources of the computer system managed by the operating system, such as files and the like.

[0016] The operating system provides several application programming interfaces 106 that are accessed by applications 104 . These APIs 106 are described by one or more metadata files 108 . Metadata file 108 is a machine-readable, programming language-independent representation of the operating system's API or APIs. As described below, such a metadata file can be automatically created from an API description file, thus allowing the au...

Abstract

Native operating system application programming interfaces (APIs) are described using metadata and such descriptions are stored in a standard file format in a known location. By storing API definitions using such metadata, other applications can readily identify and use the APIs. To create such API representations, during development, a developer describes the shape of the API, including (but not limited to) the classes, interfaces, methods, properties, events, parameters, structures and enumerated types defined by the API. This API description is processed by a tool which generates a machine-readable metadata file. The machine-readable metadata file contains the same information as the API description, however in a format designed to be machine read rather than human authored.

Description

Background technique [0001] Operating systems typically have several application programming interfaces that allow applications to access functionality supported by the operating system. Such APIs are typically specified by the operating system through the use of named files or objects in some computer programming language. For example, the C programming language uses header files that may have names such as "interface.h". Likewise, in C#, a mechanism called "P / Invoke" signing is used to access operating system APIs. A person writing a computer program that will utilize an operating system API typically includes a reference in the program to a named API file or object, or uses another mechanism provided by the programming language. The program then includes, for example, calls to functions defined by the API in accordance with the syntax used by the API. [0002] APIs defined in this way are not directly accessible by languages ​​other than the language in which they were w...
