HLOAPI3 ;ALB/CJM-HL7 - Developer API's for sending application acks ;03/13/2007
|
|
;;1.6;HEALTH LEVEL SEVEN;**126,133,134**;Oct 13, 1995;Build 30
|
|
;Per VHA Directive 2004-038, this routine should not be modified.
|
|
;
|
|
BATCHACK(HLMSTATE,PARMS,ACK,ERROR) ;Starts a batch message that is the response to a batch message. Individual acks are placed in the batch by calling $$ADDACK.
|
|
;$$SENDACK^HLOAPI2 must be called when the batch of acks is complete. The return destination is determined automatically from the original message.
|
|
;
|
|
;Input:
|
|
; HLMSTATE (pass by reference, required) the array obtained by calling $$STARTMSG^HLOPRS when parsing the original message
|
|
; PARMS (optional, pass by reference) These subscripts may be defined:
|
|
; "ACCEPT ACK RESPONSE")=<tag^routine> to call when the commit ack is received (optional)
|
|
; "ACCEPT ACK TYPE") = <AL,NE> (optional, defaults to AL)
|
|
; "COUNTRY") - a 3 character country code from the HL7 standard table (optional)
|
|
; "ENCODING CHARACTERS" - the 4 HL7 encoding characters (optional,defaults to "^~\&"
|
|
; "FAILURE RESPONSE" (optional) the <tag>^<routine> that the sending application routine should execute if the transmission of the message fails, i.e., the message can not be sent or a requested commit ack is not received.
|
|
; "FIELD SEPARATOR" - the field separator (optional, defaults to "|")
|
|
; "QUEUE" (optional) An application can name a private queue (a string under 20 characters, namespaced). The default is the name of the queue of the original message
|
|
; "SECURITY" - security information to include in the header segment, SEQ 8 (optional)
|
|
; "VERSION" - the HL7 Version ID (optional, defaults to 2.4)
|
|
;Output:
|
|
; Function returns 1 on success, 0 on failure
|
|
; PARMS - left undefined upon completion
|

; ACK (pass by reference, required) the batch acknowledgment message being built.

ADDACK(ACK,PARMS,ERROR) ;This API adds an application acknowledgment to a batch

|
|
;The Default behavior is to return a general application ack.
|
|
;The application may optionally specify the message
|
|
;type and event and/or call $$ADDSEG^HLOAPI to add segments.
|
|
;A generic MSA segment (components 1-3) will be added automatically
|

;if the application doesn't call $$ADDSEG^HLOAPI to add an MSA segment
