|---|
| unsigned long | XxcTransaction | char * pszServer [in] XX1 Server ip-address or URL
int port [in] XX1 Server SOAP port
char * pszCertificate [in] PGP: optional, path and file name of certificate databaseSSL: optional, path of certificate databases
char * pszTC [in] Transaction Control Data as XML format
char * pszReq[in] Request message as XML format
int cbReq[in] Length of request message in pszReq
char ** ppszRspTC[out] Returned Transaction Control Data as XML format
char ** ppszRsp[out] Response message as XML format
int * pcbRsp[out] Length of response message in ppszRsp
char ** ppszErrorunsigned long ulTimeout[in] Socket connect timeout in seconds or XXC_DEFAULTTIMEOUT
unsigned long ulFlags
 | Sends a stateless transaction to the server.  Return Values:  If no error occurs, the return code is XXC_OK (0) and ppszRsp contains the response XML.
 Remarks: XxcFreeBuffer must be called on all returned strings. 
 | 
| HXXCONTEXT | XxcGetSession | char * pszServer [in] XX1 Server ip-address or URL
int port [in] XX1 Server SOAP port
char * pszCertificate [in] PGP: optional, path and file name of certificate databaseSSL: optional, path of certificate databases
char * pszTC [in] Transaction Control Data as XML format
char ** ppszErrorunsigned long pulStatusunsigned long ulTimeout[in] Socket connect timeout in seconds or XXC_DEFAULTTIMEOUT
unsigned long ulFlags
 | Obtains a session context from the host and locks it for other users.  Return Values:  If no error occurs, the return code is a context handle and pulStatus is set to XXC_OK. On error the return value is NULL and pulStatus contains the error code. 
  Remarks: XxcFreeBuffer must be called on all returned strings.Use XxcReleaseSession when done with sessioned transactions to unlock the host context. 
 | 
| unsigned long | XxcReleaseSession | HXXCONTEXT hContext [in] Context handle returned by XxcGetSession function
char * pszTC [in] Transaction Control Data as XML format
char ** ppszErrorunsigned long ulFlags
 | Releases context obtained with XxcGetSession and unlocks the session on the host.  Return Values:  If no error occurs, the return code is XXC_OK (0). 
  Remarks:  XxcFreeBuffer must be called on all returned strings. Connections will be closed. The XXF_HTTPKEEPALIVE flag has no effect. 
 | 
| unsigned long | XxcSessionedTransaction | HXXCONTEXT hContext [in] Context handle returned by XxcGetSession function
char * pszTC [in] Transaction Control Data as XML format
char * pszReq[in] Request message as XML format
int cbReq[in] Length of request message in pszReq
char ** ppszRspTC[out] Returned Transaction Control Data as XML format
char ** ppszRsp[out] Response message as XML format
int * pcbRsp[out] Length of response message in ppszRsp
char ** ppszErrorunsigned long ulFlags
 | Sends a transaction to the server using a host context.  Return Values:  If no error occurs, the return code is XXC_OK (0) and ppszRsp contains the response XML. 
  Remarks:  XxcFreeBuffer must be called on all returned strings. It is highly recommended to use the XXF_HTTPKEEPALIVE flag with all sessioned transactions.

| void | XxcFreeBuffer | char * pszBuffer[in] String returned by any function/parameter
 | Frees memory allocated for returned strings.  Remarks:  This function must be called on all returned string (char *) parameters after each invocation of the following functions:XxcTransactionXxcSessionedTransactionXxcGetSessionXxcReleaseSession

			Transaction Flags can be combined with & like this: 
unsigned long ulflags = XXF_SSL & XXF_HTTPKEEPALIVE;
Can be a combined of the following:
| Flag Code | Meaning | 
|---|
| XXF_NOCOMPRESSION | Do not compress data streams. | 
| XXF_NATIVEDATA | Request XML is native provider data format. | 
| XXF_ENCRYPT | Apply PGP 128-bit encryption on data streams (port 8800) | 
| XXF_SSL | Apply SSL3 and TLS with 128-bit encryption (default port 443) | 
| XXF_HTTPKEEPALIVE | Keeps TCP/IP socket connection alive. | 
 
	
		
	
		
		
			
		
			
		
			| Error Code | Meaning | 
|---|
| XXC_ERR_MEMORY | Not enough memory. | 
| XXC_ERR_PARAMETER | Invalid parameter. | 
| XXC_ERR_SOCKETCONNECT | Can't connect to server. | 
| XXC_ERR_SOCKETREAD | Socket receive failed. | 
| XXC_ERR_SOCKETWRITE | Socket send failed. | 
| XXC_ERR_SOAP | Server rejected SOAP envelope. | 
| XXC_ERR_NOSESSIONAVAILABLE | Server busy. | 
| XXC_ERR_SSLINIT | The SSL certification databases were invalid or not found. |
