- * This function must be called on a client returned by avio_accept() before
- * using it as a read/write context.
- * It is separate from avio_accept() because it may block.
- * A step of the handshake is defined by places where the application may
- * decide to change the proceedings.
- * For example, on a protocol with a request header and a reply header, each
- * one can constitute a step because the application may use the parameters
- * from the request to change parameters in the reply; or each individual
- * chunk of the request can constitute a step.
- * If the handshake is already finished, avio_handshake() does nothing and
- * returns 0 immediately.
- *
- * @param c the client context to perform the handshake on
- * @return 0 on a complete and successful handshake
- * > 0 if the handshake progressed, but is not complete
- * < 0 for an AVERROR code
