```
#include "ZeroTierSockets.h"
int main()
{
zts_node_start();
zts_net_join(net_id);
int fd = zts_bsd_socket(ZTS_AF_INET, ZTS_SOCK_STREAM, 0);

# Build from source (optional)
```
git submodule update --init
```
This project uses [CMake](https://cmake.org/download/) as a build system generator. The scripts `build.*` simplify building and packaging for various targets. There are many targets and configurations not mentioned here.
|Platform| Build instructions | Notes |
|:---|:---|:---|
|Linux | `./build.sh host "release"`| [build.sh](./build.sh) |
|macOS | `./build.sh host "release"`| [build.sh](./build.sh) |
|Windows | `. .\build.ps1; Build-Host -BuildType "Release" -Arch "x64"` | [build.ps1](./build.ps1), *Requires [PowerShell](https://github.com/powershell/powershell)*|
Using the `host` keyword will automatically detect the current machine type and build standard libzt for use in C/C++ (no additional language bindings.) See `./build.sh list` for additional target options. `libzt` depends on [cURL](https://github.com/curl/curl) for the optional portion of the API that interfaces with our hosted web offering ([my.zerotier.com](my.zerotier.com)). If you do not need this functionality you can omit it by passing `-DZTS_DISABLE_CENTRAL_API=1` to CMake.
Example output:
```
~/libzt/dist/macos-x64-host-release
├── bin
│ ├── client
│ ├── server
│ └── ...
└── lib
├── libzt.a
└── libzt.dylib
```
Important directories:
|Directory| Purpose|
|:---|:---|
|`dist`| Contains finished targets (libraries, binaries, packages, etc.)|
|`cache`| Contains build system caches that can safely be deleted after use.|
|`pkg`| Contains project, script and spec files to generate packages.|
