Application Programming Interfaces

Sample C++

Example of object creation in an RTR server program.

server code

 

void CombinationOrderProcessor::StartProcessingOrdersAtoL()

{

//

//Create an RTRKeySegment for all ASCII values between "A" and "L."

m_pkeyRange = new RTRKeySegment (rtr_keyseg_string, //To process strings.

1,//Length of the key. OffsetIntoApplicationProtocol, //Offset value.

"A",

//Lowest ASCII value for partition.

"L");

//Highest ASCII value for partition.

StartProcessingOrders(PARTITION_NAMEAToL,m_pKeyRange);

}

//

//Create an RTRData Oobject to hold each incoming message or event. This

//object will be reused.

//

RTRData *pDataReceived= new RTRData();

//

//Continually loop, receiving messages and dispatching them to the handlers.

while(true)

{

sStatus = pTransaction->Receive(&pDataReceived); ASSERT(RTR_STS_OK == sStatus);

sStatus = pDataReceived->Dispatch(); ASSERT(RTR_STS_OK == sStatus);

}

RTR C

You can use the C programming interface to write C applications

Programming

that use RTR. For more information on the C programming

Interface

interface, see the RTR C Application Programmer's Reference

 

Manual and the RTR Application Design Guide.

 

Snippets from client and server programs using the RTR C-

 

programing API follow and are more fully shown in the RTR

 

Application Design Guide.
