# bsdsocket.library — BSD Socket API
|
||
|
||
## Overview
|
||
|
||
`bsdsocket.library` is the AmigaOS implementation of the BSD socket API. It is provided by the active TCP/IP stack (AmiTCP, Miami, Roadshow) and presents a POSIX-like socket interface adapted to the Amiga's library-based architecture.
|
||
|
||
---
|
||
|
||
## Opening
|
||
|
||
```c
|
||
struct Library *SocketBase = OpenLibrary("bsdsocket.library", 4);
|
||
if (!SocketBase) { /* no TCP/IP stack running */ }
|
||
```

||
## WaitSelect — Amiga-Enhanced select()
|
||
|
||
Unlike BSD `select()`, `WaitSelect` integrates with Exec signals:
|
||
|
||
```c
|
||
fd_set rdset;
|
||
FD_ZERO(&rdset);
|
||
FD_SET(sock, &rdset);
|
||
|
||
ULONG sigmask = SIGBREAKF_CTRL_C; /* also wait for Ctrl-C */
|
||
struct timeval tv = { 5, 0 }; /* 5 second timeout */
|
||
|
||
LONG n = WaitSelect(sock + 1, &rdset, NULL, NULL, &tv, &sigmask);
|
||
if (n > 0 && FD_ISSET(sock, &rdset)) { /* data ready */ }
|
||
if (sigmask & SIGBREAKF_CTRL_C) { /* user pressed Ctrl-C */ }
|
||
```
|
||
|

|
||
|
||
## Simple TCP Client
|
||
|
||
```c
|
||
LONG sock = socket(AF_INET, SOCK_STREAM, 0);
|
||
struct sockaddr_in addr;
|
||
addr.sin_family = AF_INET;
|
||
addr.sin_port = htons(80);
|
||
addr.sin_addr.s_addr = inet_addr("93.184.216.34");
|
||
|
||
if (connect(sock, (struct sockaddr *)&addr, sizeof(addr)) == 0) {
|
||
send(sock, "GET / HTTP/1.0\r\nHost: example.com\r\n\r\n", 38, 0);
|
||
char buf[4096];
|
||
LONG n = recv(sock, buf, sizeof(buf) - 1, 0);
|
||
buf[n] = 0;
|
||
Printf("%s\n", buf);
|
||
}
|
||
CloseSocket(sock);
|
||
```
