## Functions
static int | soap_wsrm_init (struct soap *soap, struct soap_wsrm_data *data, void *arg)
| Initializes plugin data.
static int | soap_wsrm_copy (struct soap *soap, struct soap_plugin *p, struct soap_plugin *q)

int | soap_wsrm_create (struct soap *soap, const char *to, const char *acksto, LONG64 expires, const char *wsa_id, soap_wsrm_sequence_handle *seq)
| Creates a new sequence. Sequences are usually created by the sender (client) and confirmed by the receiver (server). The 'to' server address must be used for all messages of the sequence to be sent to the WS-RM destination server. Optionally the 'replyto' address can be given of the WS-RM source to reply to. A sequence ID is generated by the server upon success.
int | soap_wsrm_create_offer (struct soap *soap, const char *to, const char *replyto, const char *id, LONG64 expires, enum wsrm__IncompleteSequenceBehaviorType behavior, const char *wsa_id, soap_wsrm_sequence_handle *seq)
| Creates a new sequence by offering suggested WS-RM parameters to the WS-RM destination. Sequences are usually created by the sender (client) and confirmed by the receiver (server). The 'to' server address must be used for all messages of the sequence to be sent to the WS-RM destination server. Optionally the 'replyto' address can be given of the WS-RM source to reply to. A sequence ID is generated by the server upon success.

| Creates a new sequence by offering suggested WS-RM parameters to the WS-RM destination. Sequences are usually created by the sender (client) and confirmed by the receiver (server). The 'to' server address must be used for all messages of the sequence to be sent to the WS-RM destination server. Optionally the 'replyto' address can be given of the WS-RM source to reply to and an 'acksto' address can be given for acknowledgement messages to be sent to (normally to the reply to). A sequence ID is generated by the server upon success.
int | soap_wsrm_request_num (struct soap *soap, soap_wsrm_sequence_handle seq, const char *wsa_id, const char *wsa_action, ULONG64 num)
| Adds a WS-RM sequence message number to the next message transmitted. No acks are requested.
int | soap_wsrm_request (struct soap *soap, soap_wsrm_sequence_handle seq, const char *wsa_id, const char *wsa_action)
| Adds a WS-RM sequence message number to the next message transmitted to the WS-RM destination and increments the message counter by one. No acks are requested.
int | soap_wsrm_request_acks (struct soap *soap, soap_wsrm_sequence_handle seq, const char *wsa_id, const char *wsa_action)

int | soap_wsrm_check_retry (struct soap *soap, soap_wsrm_sequence_handle seq)
| Client-side check to verify if the remote call can be retried when a failure occured. Increases the robustness of messages sends, by ensuring that the message was at least transmitted (but not necessarily received). Also implements HTTP 307 Temporary Redirect. Retries are limited to SOAP_WSRM_MAX_RETRIES iterations.
int | soap_wsrm_resend (struct soap *soap, soap_wsrm_sequence_handle seq, ULONG64 lower, ULONG64 upper)
| Client-side call to resend all non-acknowledged messages that were automatically cached for this sequence. Messages stored in the sequence for retransmission (those that were previously sent but not acknowledged) are resent to the soap_wsrm_to() address, which was set by soap_wsrm_create() or soap_wsrm_create_offer(). It is recommended to resend messages after the last message in the sequence was transmitted before closing the sequence. To reduce unnecessary resend attempts, it is recommended to use soap_wsrm_request_ack() with the last message to request acks for messages already delivered.
int | soap_wsrm_close (struct soap *soap, soap_wsrm_sequence_handle seq, const char *wsa_id)
| Closes the sequence, but does not yet terminate it. No new messages should be send, but messages can be resend with soap_wsrm_resend() if desired.
int | soap_wsrm_terminate (struct soap *soap, soap_wsrm_sequence_handle seq, const char *wsa_id)

int | soap_wsrm_pulse (struct soap *soap, int timeout)
| Sends acknowledgements for all open sessions to all peers. Must set send and recv timeouts to prevent blocking.
int | soap_wsrm_acknowledgement (struct soap *soap, soap_wsrm_sequence_handle seq, const char *wsa_id)
| Sends acknowledgements.
void | soap_wsrm_seq_free (struct soap *soap, soap_wsrm_sequence_handle seq)
| Must be called to free the sequence allocated by soap_wsrm_create() or by soap_wsrm_create_offer(). Sequences created by soap_wsrm_create_offer return handles that are not automatically reclaimed by the engine.
const char * | soap_wsrm_to (soap_wsrm_sequence_handle seq)
| Returns the endpoint address of the destination service that serves the sequence. Initially set with soap_wsrm_create or soap_wsrm_create_offer. HTTP 307 Temporary Redirect can change the endpoint during the lifetime of a message sequence. Thus, this function returns the most recent endpoint binding that can be used to send message to the server endpoint.
const char * | soap_wsrm_acksto (soap_wsrm_sequence_handle seq)
| Returns the endpoint address of the AcksTo acknowledgement service that serves the sequence, when set with soap_wsrm_create() or soap_wsrm_create_offer() or NULL otherwise.

int | soap_wsrm_reply_num (struct soap *soap, int flag)
| Prepares reply from service. When flag is set, adds a WS-RM sequence message number to the next message transmitted. No acks are requested. No WS-Addressing relay.
int | soap_wsrm_reply (struct soap *soap, const char *wsa_id, const char *wsa_action)
| Server-side server operation reply to be performed when the service operation returns. Server operations that support WS-Addressing and WS-RM must call this function to return normally (and allow the response to be relayed).
int | soap_wsrm_reply_request_acks (struct soap *soap, const char *wsa_id, const char *wsa_action)
| Server-side server operation reply to be performed when the service operation returns. Message acks for the current sequence are requested, but only when client made a create sequence offer. Server operations that support WS-Addressing and WS-RM must call this function or soap_wsrm_reply() to return normally (and allow the response to be relayed).
void | soap_wsrm_cleanup (struct soap *soap)
| Cleans up all expired sequences and releases resources. To be used at the server side to periodically clean up WS-RM sequences. Server-side cleanup is automatic, as long as WS-RM is in use. Does not release client-side sequences allocated by soap_wsrm_create() or soap_wsrm_create_offer().

| ) |  |

Creates a new sequence by offering suggested WS-RM parameters to the WS-RM destination. Sequences are usually created by the sender (client) and confirmed by the receiver (server). The 'to' server address must be used for all messages of the sequence to be sent to the WS-RM destination server. Optionally the 'replyto' address can be given of the WS-RM source to reply to and an 'acksto' address can be given for acknowledgement messages to be sent to (normally to the reply to). A sequence ID is generated by the server upon success.

Parameters

  | soap | context
  [in] | to | endpoint address of the WS-RM destination server (required)
  [in] | replyto | endpoint address of the WS-RM source (optional)
  [in] | acksto | endpoint address for WS-RM acknowledgements (optional) (optional, use NULL when acks are piggy-backed on response messages to the source)
  [in] | id | offered WS-RM sequence identifier (optional, generate with NULL)
  [in] | expires | max sequence duration (its lifetime) in ms (use 0 for inifinite)
  [in] | behavior | offered DiscardEntireSequence, DiscardFollowingFirstGap, or NoDiscard, which specifies the WS-RM destination's action when a sequence is closed/terminated when it is incomplete, and notifies the source when failed.
  [in] | wsa_id | WS-Addressing message ID (optional, use NULL when omitted)
