These sends can take time, which can be controlled with the soap context connect_timeout, send_timeout, recv_timeout settings.

Parameters

  | soap | context
  [in] | seq | pointer to sequence
  [in] | nack | num of nack message, 0 to generate acks

When NoDicards behavior is set, out of sequence messages will be discared until message sequence has resumed (requires peer resends).

Parameters

  soap | context

Returns
  SOAP_OK or SOAP_STOP (duplicate message error, MUST be returned by the service operation executing the soap_wsrm_check) or an error code.

Do not use this function in a ReplyTo response-accepting destination service operation.

Parameters

  soap | context
  timeout | NoDiscard behavior: 0=discard messages out of sequence to immediately resume, >0 wait (in seconds) until message sequence has resumed while sending Nacks every second to indicate messages are required to continue the flow of messages, <0 wait (in microseconds) until message sequence has resumed, send one nack when timeout occurred.
