|  | const char * | endpoint,

SOAP_FMAC1 void SOAP_FMAC2 soap_wsdd_init_ProbeMatches | ( | struct soap * | soap,
|  | struct wsdd__ProbeMatchesType * | matches
| ) |  |

Initalize the probe matches container.

Parameters

  soap | context
  matches | the container with matches to initialize

SOAP_FMAC1 int SOAP_FMAC2 soap_wsdd_listen | ( | struct soap * | soap,
|  | int | timeout
| ) |  |

Listen on a port for inbound WS-Discovery messages, also cleans up memory with `soap_destroy` and `soap_end`.

Parameters

  | soap | context
  [in] | timeout | seconds to listen (use negative value for micro seconds)

Returns
  SOAP_OK or error code

First you need to open a port with soap_bind(soap). Then invoke this function to listen to WS-Discovery messages on that port. Inbound messages are accepted and the information is relayed to the event handlers, see Section WS-Discovery Event Handlers. Use soap->user to pass a pointer to a state object that the event hanlders can use. The timeout allows a Client to periodically poll the port for messages. A value of zero will loop the listener forever or until an error occurs.

SOAP_FMAC1 int SOAP_FMAC2 soap_wsdd_Probe | ( | struct soap * | soap,
|  | soap_wsdd_mode | mode,
|  | soap_wsdd_to | to,

|  | const char * | Types,
|  | const char * | Scopes,
|  | const char * | MatchBy
| ) |  |

Client Probe message to a TS or DP.

Parameters

  | soap | context
  [in] | mode | SOAP_WSDD_MANAGED or SOAP_WSDD_ADHOC
  [in] | to | SOAP_WSDD_TO_TS or SOAP_WSDD_TO_DP
  [in] | endpoint | to send Probe to (unicast or multicast)
  [in] | MessageID | WS-Addressing message ID of the message
  [in] | ReplyTo | WS-Addressing ReplyTo message ID of the message
  [in] | Types | an unordered string of QNames to probe
  [in] | Scopes | an unordered set of scopes to probe
  [in] | MatchBy | matching rule to apply for this probe

Returns
  SOAP_OK or error code

A Client sends a probe to find Target Services by the Type of the Target Service, a Scope in which the Target Service resides, both, or simply all Target Services. The matches will be delivered to wsdd_event_ProbeMatches when soap_wsdd_listen receives a ProbeMatch response. The RelatesTo of the ProbeMatches is the MessageID of the Probe.

SOAP_FMAC1 int SOAP_FMAC2 soap_wsdd_ProbeMatches | ( | struct soap * | soap,
|  | const char * | endpoint,
|  | const char * | MessageID,
|  | const char * | RelatesTo,

Returns
  SOAP_OK or error code

A Client sends a probe to find Target Services by the Type of the Target Service, a Scope in which the Target Service resides, both, or simply all Target Services. The Target Server(s) or Discovery Proxy responds by sending ProbeMatches to the Client.

  [in] | EndpointReference | of the Target Service or Discovery Proxy

Returns
  SOAP_OK or error code

A Client sends a resolve to locate a Target Service, i.e., to retrieve its transport address(es). This server-side event handler returns the match(es). The matches will be delivered to wsdd_event_ResolveMatches when soap_wsdd_listen receives a ResolveMatch response. The RelatesTo of the ResolveMatches is the MessageID of the Resolve.
