ZeroTier SDK
======

[![irc](https://img.shields.io/badge/IRC-%23zerotier%20on%20freenode-orange.svg)](https://webchat.freenode.net/?channels=zerotier)

Embed ZeroTier directly into your app or service. Connect everything without worrying about how it's actually connected.
***

## Example

```
string str = "welcome to the machine";
zts_start("./zt");
while(!zts_service_running())
	sleep(1);
zts_join_network(nwid);
int err, sockfd;
while(!zts_has_address(nwid))
	sleep(1);
if((fd = zts_socket(AF_INET, SOCK_STREAM, 0)) < 0) {
	printf("error creating ZeroTier socket");
}
if((err = zts_connect(fd, (const struct sockaddr *)addr, sizeof(addr))) < 0) {
	printf("error connecting to remote host (%d)\n", err);
}
int wrote = zts_write(fd, str.c_str(), str.length());
zts_close(fd);
```

Bindings also exist for [many popular languages]().

## Build Targets
### Static Library
 - `make static_lib`: Will output to `build/`

### Tests
 - `make tests`: Will output to `build/tests/`

Then run the unit test suite with whatever configuration you need. For instance:

To run a single-test IPv4 client/server test:

  - Host 1: `./build/test/unit zt1 c7cd7c9e1b0f52a2 simple 4 server 8787`
  - Host 2: `./build/test/unit zt2 c7cd7c9e1b0f52a2 simple 4 client 10.9.9.40 8787`

To run a multi-message IPv4 client/server test:
  - Host 1: ./build/test/unit zt2 c7cd7c9e1b0f52a2 simple 4 server 8787 n_bytes 100 50'
  - Host 2: ./build/test/unit zt2 c7cd7c9e1b0f52a2 simple 4 client 10.9.9.40 8787 n_bytes 100 50'

  - For more unit test examples, see the [testing]() page
