The examples in this chapter assume that a structure was set up to store information about the ORCA session when the session was opened. In the examples, the variable lpORCA_Info is a pointer to an instance of this structure:
typedef struct ORCA_Info {
LPTSTR lpszErrorMessage; // Ptr to message text
HPBORCA hORCASession; // ORCA session handle
DWORD dwErrorBufferLen; // Length of error buffer
long lReturnCode; // Return code
HINSTANCE hLibrary; // Handle to ORCA library
PPBORCA_CONFIG_SESSION pConfig; // ConfigureSession
} ORCA_INFO, FAR *PORCA_INFO;
