Macro Definition Documentation

HTTP_ERR_MSG

#define HTTP_ERR_MSG   "HTTP/1.0 400 Bad Request\n"

Message sent to clients that do not send a valid get request.

Enumeration Type Documentation

http_client_status

enum http_client_status

The possible states of a client from the server's POV.

Enumerator
HTTP_CONNECTED	We accepted the connection on the tcp socket.
HTTP_GOT_GET_REQUEST	Successfully received the get request.
HTTP_STREAMING	Connection is ready for sending audio data.
HTTP_INVALID_GET_REQUEST	We didn't receive a valid get request.

The HTTP sender.

This is the only sender which does not FEC-encode the stream. This is not necessary because HTTP sits on top of TCP, a reliable transport which retransmits lost packets automatically. The sender employs per-client queues which queue chunks of audio data if they can not be sent immediately because the write operation would block. Most methods of the sender are implemented as wrappers for the generic functions defined in send_common.c.
