int | soap_wsrm_check (struct soap *soap)
| Server-side check for the presence of WS-Addressing and WS-RM header blocks in the SOAP header. Also prepares the return WS-RM header. This function should be called in the each service operation that supports WS-RM. Do not use this function in a ReplyTo response-accepting destination service operation.
int | soap_wsrm_reply (struct soap *soap, const char *wsa_id, const char *wsa_action)

|  | 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. Message acks for the current sequence are requested. Parameters:
  | soap | context
  | seq | sequence handle set by soap_wsrm_create() or soap_wsrm_create_offer()
  `[in]` | wsa_id | WS-Addressing message ID (optional, use NULL when omitted)
  `[in]` | wsa_action | mandatory WS-Addressing action of the next message sent
Returns: SOAP_OK or error code

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 to the WS-RM destination. No acks are requested. Parameters:
  | soap | context
  | seq | sequence handle set by soap_wsrm_create() or soap_wsrm_create_offer()
  `[in]` | wsa_id | WS-Addressing message ID (optional, use NULL when omitted)
  `[in]` | wsa_action | mandatory WS-Addressing action of the next message sent
  `[in]` | num | WS-RM sequence message number
Returns: SOAP_OK or error code

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. Parameters:
  | soap | context
  | seq | sequence handle set by soap_wsrm_create or soap_wsrm_create_offer
  `[in]` | lower | resend message range lower bound (0 for lowest)
  `[in]` | upper | resend message range upper bound (or 0 for infinite)
Returns: SOAP_OK or error code (can be ignored when resends are retried later)

int soap_wsrm_resend_seq | ( | struct soap * | soap,

int soap_wsrm_send | ( | struct soap * | soap,
|  | const char * | buf,
|  | size_t | len
| ) | `[static]`

  | Internal callback function to override fsend(). When the wsrm plugin is enabled, saves the message to the current sequence that is created at the client side. Allows unacknowledged messages to be resend with soap_wsrm_resend(). Parameters:
  | soap | context
  `[in]` | buf | message data
  `[in]` | len | message data length
Returns: SOAP_OK or error code

int soap_wsrm_sender_fault | ( | struct soap * | soap,
|  | const char * | faultstring,
|  | const char * | faultdetail
| ) |

  | Sets sender SOAP Fault for server faults (can be user defined faults). When called before soap_wsrm_check() in the server operation, terminates the current sequence. Otherwise, the sequence is not terminated. In either case the fault is returned to sender (client) or to the FaultTo server when the WS-Addressing FaultTo header was set by the sender. Parameters:
  | soap | context
  `[in]` | faultstring | fault string
  `[in]` | faultdetail | detail string
Returns: SOAP_FAULT

int soap_wsrm_sender_fault_subcode | ( | struct soap * | soap,
|  | const char * | faultsubcode,
|  | const char * | faultstring,
|  | const char * | faultdetail
| ) |

  | Sets sender SOAP Fault (sub)code for server faults (can be user defined faults). When called before soap_wsrm_check() in the server operation, terminates the current sequence. Otherwise, the sequence is not terminated. In either case the fault is returned to sender (client) or to the FaultTo server when the WS-Addressing FaultTo header was set by the sender. Parameters:
  | soap | context
  `[in]` | faultsubcode | sub code string
  `[in]` | faultstring | fault string
  `[in]` | faultdetail | detail string
Returns: SOAP_FAULT

int soap_wsrm_seq_append | ( | struct soap * | soap,
|  | struct soap_wsrm_data * | data,
|  | const char * | buf,
|  | size_t | len
| ) | `[static]`

  | Internal function used by soap_wsrm_send() to append message data to the current message being transmitted for the current sequence. Parameters:
  | soap | context
  | data | plugin
  `[in]` | buf | message data
  `[in]` | len | message data length
Returns: SOAP_OK or error code

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(). Sequence handles are not automatically reclaimed by the engine. Parameters:
  | soap | context
  | seq | sequence handle set by soap_wsrm_create() or soap_wsrm_create_offer()

struct soap_wsrm_sequence * soap_wsrm_seq_insert | ( | struct soap * | soap,
|  | struct soap_wsrm_data * | data
| ) | `[static]`

  | Internal function to create a new local sequence state. Parameters:
  | soap | context
  | data | plugin
Returns: sequence or NULL

struct soap_wsrm_sequence * soap_wsrm_seq_lookup | ( | const struct soap_wsrm_data * | data,
|  | const char * | id
| ) | `[static]`

  | Internal function to look up sequence given its id. Parameters:
  | soap | context
  | data | plugin
  `[in]` | sequence | identifier string
Returns: sequence or NULL

const char * soap_wsrm_seq_newid | ( | struct soap * | soap,
|  | struct soap_wsrm_data * | data
| ) | `[static]`

  | Internal function to obtain a new sequence identifier. Parameters:
  | soap | context
  | data | plugin
Returns: sequence identifier string

int soap_wsrm_seq_terminated | ( | struct soap * | soap,
|  | struct soap_wsrm_sequence * | seq
| ) | `[static]`

  | Internal function to check if a sequence is terminated or needs to be terminated when expired. Parameters:
  | soap | context
  | seq | pointer to sequence
Returns: 0 (not terminated) or 1 (terminated)

int soap_wsrm_set_ack | ( | struct soap * | soap,
|  | struct soap_wsrm_sequence * | seq,
|  | struct _wsrm__SequenceAcknowledgement * | ack
| ) | `[static]`

  | Internal function called by soap_wsrm_add_acks() to populate the SequenceAcknowledgement header block. Parameters:
  | soap | context
  `[in]` | seq | pointer to sequence
  `[out]` | ack | pointer to SequenceAcknowledgement to populate

int soap_wsrm_terminate | ( | struct soap * | soap,
|  | soap_wsrm_sequence_handle | seq,
|  | const char * | wsa_id
| ) |

  | Terminates the sequence. No new messages should be send and no resends should be tried. Usually done after soap_wsrm_close() or any time to terminate the sequence prematurely. Parameters:
  | soap | context
  | seq | sequence handle set by soap_wsrm_create or soap_wsrm_create_offer
  `[in]` | wsa_id | WS-Addressing message ID (optional)
Returns: SOAP_OK or error code

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. Parameters:
  | seq | sequence handle set by soap_wsrm_create() or soap_wsrm_create_offer()
Returns: the sequence endpoint address
