# P/Invoke

**⚠ NOTICE: [Check out CsWin32](https://github.com/dotnet/pinvoke/issues/565): A new, preferred approach for Win32 p/invokes now exists for C# developers.**

This repo is no longer maintained.

---

A collection of libraries intended to contain all P/Invoke method signatures for popular operating systems.
Think of it as https://pinvoke.net, but proven to compile and work properly, and often
with sample usage in the form of unit tests.

A unique C# project wraps each native library.
The C# project may multi-target in order to support many versions of .NET Framework, .NET Core and .NET Standard.

Win32 APIs for all Windows versions are welcome.
Special Windows Store targeted assemblies omit p/invoke signatures to banned APIs so your Store apps can depend on these libraries without getting rejected by the Store certification process.

This project is supported by the [.NET Foundation](https://dotnetfoundation.org).

## Usage

Install the NuGet package(s) for the DLLs you want to P/Invoke into.
For example, if you want to P/Invoke into Win32's BCrypt.dll, install this package:

```powershell
Install-Package PInvoke.BCrypt
```

Then import the following namespaces, as demonstrated below (if using C# 6):

```csharp
using PInvoke;
using static PInvoke.BCrypt; // Supported in C# 6 (VS2015) and later.
```

This will allow you to conveniently call these methods directly by method name:

```csharp
var error = BCryptOpenAlgorithm(AlgorithmIdentifiers.BCRYPT_SHA256_ALGORITHM); // C# 6 syntax
var error = BCrypt.BCryptOpenAlgorithm(BCrypt.AlgorithmIdentifiers.BCRYPT_SHA256_ALGORITHM); // C# 5 syntax
```

Sometimes a PInvoke method may have multiple overloads. For example every method that accepts
`struct*` parameters has an overload that accepts `IntPtr` in its place. In other cases there
may be overloads that accept `struct*` and `struct?`. In some of these cases that can lead to
compiler errors if you pass in `null` because both `struct*` and `struct?` overloads can match.
To resolve the issue, add a cast to your null: `(struct?)null` to resolve the ambiguity.

### What if I need custom `uint` value not provided in `enum`?

Cast any `uint` to specific `enum` type and pass as parameter.

## Design goals

Provide a slightly higher than lowest level API for P/Invoke signatures.
For example, instead of `IntPtr` parameters and `uint` flags, you'll see `SafeHandle`-derived
types as parameters and flags `enum` types. API documentation will be provided via XML doc comments
for easy reading with Intellisense, along with links to the describing pages on MSDN
or elsewhere as applicable.

In some cases we offer several overloads of a given native method to offer native pointer and
`IntPtr` access. We encourage folks to try writing C# `unsafe` code before using `IntPtr` because
it (ironically) can often be easier to write correct and efficient code using native pointers than
all the casting and `Marshal` call overhead that `IntPtr` requires.
Note that when a method's only use of a native pointer is its return type, the `IntPtr` returning
variant must be given a different method name by CLR overloading rules, so look for the same method
but with an `_IntPtr` suffix.

## Distribution

This library should be available on NuGet for easy consumption by your projects.
You may also copy and paste the P/Invoke signatures you need directly into your projects if desired.
