-# WASI Core API
-
-This is the API-level documentation for WASI Core. The function names
-are prefixed with "\_\_wasi\_" to reflect how they are spelled in
-flat-namespace contexts, however at the wasm module level, they are
-unprefixed, because they're inside a module namespace (currently
-"wasi\_unstable").
-
-Functions that start with `__wasi_fd_` operate on file descriptors,
-while functions that start with `__wasi_path_` operate on filesystem
-paths, which are relative to directory file descriptors.
-
-Much inspiration and content here is derived from [CloudABI] and [POSIX],
-though there are also several differences from CloudABI and POSIX. For
-example, WASI Core has no concept of processes in the traditional Unix
-sense. While wasm linear memories have some of the aspects of processes,
-and it's possible to *emulate* the full semantics of processes on top of
-them, this can sometimes be unnatural and inefficient. The goal for
-WASI Core is to be a WebAssembly-native API that exposes APIs that fit
-well into the underlying WebAssembly platform, rather than to directly
-emulate other platforms.
-
-This is also a work in progress, and the API here is still evolving.

-Atomically replace a file descriptor by renumbering another
-file descriptor.
-
-Due to the strong focus on thread safety, this environment
-does not provide a mechanism to duplicate or renumber a file
-descriptor to an arbitrary number, like dup2(). This would be
-prone to race conditions, as an actual file descriptor with the
-same number could be allocated by a different thread at the same
-time.
-
-This function provides a way to atomically renumber file
-descriptors, which would disappear if dup2() were to be
-removed entirely.
-
-Inputs:
-
-- [\_\_wasi\_fd\_t](#fd) from

-# WebAssembly System Interface Subgroup Charter
-
-The System Interface Subgroup is a sub-organization of the
-[WebAssembly Community Group](https://www.w3.org/community/webassembly/) of the W3C.
-As such, it is intended that its charter align with that of the CG. In particular,
-the sections of the [CG charter](https://webassembly.github.io/cg-charter/) relating to
-[Community and Business Group Process](https://webassembly.github.io/cg-charter/#process),
-[Contribution Mechanics](https://webassembly.github.io/cg-charter/#contrib),
-[Transparency](https://webassembly.github.io/cg-charter/#transparency), and
-[Decision Process](https://webassembly.github.io/cg-charter/#decision) also apply to the Subgroup.
-
-## Goals
-
-The mission of this sugbroup is to provide a forum for pre-standardization
-collaboration on a system interface API for WebAssembly programs.
-
-## Scope
-
-The Subgroup will consider topics related to system interface APIs, including:
-
-- APIs for host filesystems, network stacks, and other resources.
-- APIs for graphics, audio, input devices
-- APIs for encryption, format conversion, and other transformations
- (particularly where hardware accelleration may be available on some plaforms)
-
-
-## Deliverables
-
-### Specifications
-The Subgroup may produce several kinds of specification-related work output:
-- Creation of new specifications in standards bodies or working
-groups (e.g. Wasm WG or TC39)
-- Creation of new specifications outside of standards bodies
-(e.g. similar to the LLVM object file format documentation in Wasm tool conventions)
-
-### Non-normative reports
-The Subgroup may produce non-normative material such as requirements
-documents, recommendations, and use cases.
-
-### Software
-The Subgroup may produce software related to Wasm system interface APIs (either
-as standalone libraries, tooling, or integration of interface-related
-functionality in existing CG software such as Binaryen or WABT). Capabilities may
-include:
-- Libraries implementing external standard APIs in terms of WebAssembly
- System Interface APIs
-- Tools for producing code that uses WebAssembly System Interface APIs
-- Tools for implementing WebAssembly APIs
-- Tools for debugging programs using WebAssembly System Interface APIs
-
-## Amendments to this Charter and Chair Selection
-
-This charter may be amended, and Subgroup Chairs may be selected by vote of the full
-WebAssembly Community Group.
