## Contributing
|

declaring that you have the right to, and actually do, grant us the rights to use your contribution. For details, visit https://cla.microsoft.com.

|
||||
For details, visit [Microsoft CLA](https://cla.microsoft.com).
|
||||
|
||||
When you submit a pull request, a CLA-bot will automatically determine whether you need to provide a CLA and decorate the PR
|
||||
appropriately (e.g., label, comment). Simply follow the instructions provided by the bot. You will only need to do this once across all repos using our CLA.

|

You will only need to do this once across all repos using our CLA.
|
||||
|
||||
We also require that contributors sign their commits using git commit -s or git commit --signoff to certify they either authored the work themselves
|
||||
or otherwise have permission to use it in this project. Please see https://developercertificate.org/ for more info, as well as to make sure that you can
|
||||
attest to the rules listed. Our CI uses the DCO Github app to ensure that all commits in a given PR are signed-off.
|
||||
Additionally, the pull request pipeline requires the following steps to be performed before
|
||||
mergining.
|
||||
|
||||
### Code Sign-Off
|
||||
|
||||
We require that contributors sign their commits using [`git commit --signoff`][git-commit-s]
|
||||
to certify they either authored the work themselves or otherwise have permission to use it in this project.
|
||||
|
||||
A range of commits can be signed off using [`git rebase --signoff`][git-rebase-s].
|
||||
|
||||
Please see [the developer certificate](https://developercertificate.org) for more info,
|
||||
as well as to make sure that you can attest to the rules listed.
|
||||
Our CI uses the DCO Github app to ensure that all commits in a given PR are signed-off.
|
||||
|
||||
### Linting
|
||||
|
||||
Code must pass a linting stage, which uses [`golangci-lint`][lint].
|
||||
The linting settings are stored in [`.golangci.yaml`](./.golangci.yaml), and can be run
|
||||
automatically with VSCode by adding the following to your workspace or folder settings:
|
||||
|
||||
```json
|
||||
"go.lintTool": "golangci-lint",
|
||||
"go.lintOnSave": "package",
|
||||
```
|
||||
|
||||
Additional editor [integrations options are also available][lint-ide].
|
||||
|
||||
Alternatively, `golangci-lint` can be [installed locally][lint-install] and run from the repo root:
|
||||
|
||||
```shell
|
||||
# use . or specify a path to only lint a package
|
||||
# to show all lint errors, use flags "--max-issues-per-linter=0 --max-same-issues=0"
|
||||
> golangci-lint run ./...
|
||||
```
|
||||
|
||||
### Go Generate
|
||||
|
||||
The pipeline checks that auto-generated code, via `go generate`, are up to date.
|
||||
|
||||
This can be done for the entire repo:
|
||||
|
||||
```shell
|
||||
> go generate ./...
|
||||
```

<!-- BEGIN MICROSOFT SECURITY.MD V0.0.7 BLOCK -->
|
||||
|
||||
## Security
|
||||
|
||||
Microsoft takes the security of our software products and services seriously, which includes all source code repositories managed through our GitHub organizations, which include [Microsoft](https://github.com/Microsoft), [Azure](https://github.com/Azure), [DotNet](https://github.com/dotnet), [AspNet](https://github.com/aspnet), [Xamarin](https://github.com/xamarin), and [our GitHub organizations](https://opensource.microsoft.com/).
|
||||
|
||||
If you believe you have found a security vulnerability in any Microsoft-owned repository that meets [Microsoft's definition of a security vulnerability](https://aka.ms/opensource/security/definition), please report it to us as described below.
|
||||
|
||||
## Reporting Security Issues
|
||||
|
||||
**Please do not report security vulnerabilities through public GitHub issues.**
|
||||
|
||||
Instead, please report them to the Microsoft Security Response Center (MSRC) at [https://msrc.microsoft.com/create-report](https://aka.ms/opensource/security/create-report).
|
||||
|
||||
If you prefer to submit without logging in, send email to [secure@microsoft.com](mailto:secure@microsoft.com). If possible, encrypt your message with our PGP key; please download it from the [Microsoft Security Response Center PGP Key page](https://aka.ms/opensource/security/pgpkey).
|
||||
|
||||
You should receive a response within 24 hours. If for some reason you do not, please follow up via email to ensure we received your original message. Additional information can be found at [microsoft.com/msrc](https://aka.ms/opensource/security/msrc).
|
||||
|
||||
Please include the requested information listed below (as much as you can provide) to help us better understand the nature and scope of the possible issue:
|
||||
|
||||
* Type of issue (e.g. buffer overflow, SQL injection, cross-site scripting, etc.)
|
||||
* Full paths of source file(s) related to the manifestation of the issue
|
||||
* The location of the affected source code (tag/branch/commit or direct URL)
|
||||
* Any special configuration required to reproduce the issue
|
||||
* Step-by-step instructions to reproduce the issue
|
||||
* Proof-of-concept or exploit code (if possible)
|
||||
* Impact of the issue, including how an attacker might exploit the issue
|
||||
|
||||
This information will help us triage your report more quickly.
|
||||
|
||||
If you are reporting for a bug bounty, more complete reports can contribute to a higher bounty award. Please visit our [Microsoft Bug Bounty Program](https://aka.ms/opensource/security/bounty) page for more details about our active programs.
|
||||
|
||||
## Preferred Languages
|
||||
|
||||
We prefer all communications to be in English.
|
||||
|
||||
## Policy
|
||||
|
||||
Microsoft follows the principle of [Coordinated Vulnerability Disclosure](https://aka.ms/opensource/security/cvd).

// This package provides utilities for efficiently performing Win32 IO operations in Go.
|
||||
// Currently, this package is provides support for genreal IO and management of
|
||||
// - named pipes
|
||||
// - files
|
||||
// - [Hyper-V sockets]
|
||||
//
|
||||
// This code is similar to Go's [net] package, and uses IO completion ports to avoid
|
||||
// blocking IO on system threads, allowing Go to reuse the thread to schedule other goroutines.
|
||||
//
|
||||
// This limits support to Windows Vista and newer operating systems.
|
||||
//
|
||||
// Additionally, this package provides support for:
|
||||
// - creating and managing GUIDs
|
||||
// - writing to [ETW]
|
||||
// - opening and manageing VHDs
|
||||
// - parsing [Windows Image files]
|
||||
// - auto-generating Win32 API code
