Sybase CEP C/C++ SDK

This chapter explains how to perform various activities in C/C++, including:

• Creating an out-of-process adapter.

• Creating an in-process adapter.

• Registering a query.

• Compiling a CCL project.

• Creating a UDF.

• Controlling the server - for example, starting or stopping a query module, or getting status information about a server or a query module.

• Embedding a Sybase CEP Server inside another process.

• C/C++ Overview
  The Sybase CEP SDK in C/C++ programming language includes the following:
• Data Types and Subroutines for UDFs and In-process Adapters
  A datatype is one of the internal forms of data used by the Sybase CEP Engine.
• APIs Used for Out-of-process Adapters and Control Programs
  The following APIs are used both by out-of-process adapters (adapters that run as separate programs rather than as part of the server process) and programs that do control activities such as compiling and executing CCL code.
• APIs Used for In-process and Out-of-process Adapters
  The following APIs can be used with both in-process and out-of-process adapters.
• Creating an Out-of-process Adapter in C/C++
  If required, you can write your own out-of-process adapter in the C/C++ programming language. You can write either an input adapter or an output adapter with C/C++.
• Creating an In-process Adapter in C/C++
  This section reviews how to write an in-process adapters in C/C++ to communicate with the Sybase CEP Server.
• Multi-Stream In-Process Adapters
  Although most adapters connect to a single stream, it is possible to connect an adapter to multiple streams.
• Setting Up Dynamic Queries and Streams with the C/C++ SDK
  The Sybase CEP C/C++ SDK includes a way to register a query.
• Control: Compile/Start/Stop/Status
  This section describes how to compile, start, and stop a project.
• Monitoring Servers and Queries
  This section provides information about monitoring servers and queries.
• Tracer Message API
  A stream can contain normal data messages and tracer messages, which you can use to calculate the time required for a message to move through .
• User-Defined Functions
  This chapter provides an overview of UDFs in C/C++.
• Querying a Public Window in C/C++
  Sybase CEP Server supports public windows, which you can query from outside the server.
• RPC Plugins
  A closer look at compiling and using Sybase CEP Remote Procedure Call (RPC) plugins. The RPC plugin enables CCL statements to call remote procedures and remote functions.
• User Authentication
  In this section, we discuss using the Sybase CEP C/C++ SDK with user authentication.
• Library-Wide Initialization and Shutdown
  This section describes how to write functions to perform library intitalization and shutdown.
