I need a running example of how to call a C++ dll funtion from a C# application.
Here is a part of the H file
#ifndef __TICKERAPI_H
#define __TICKERAPI_H
#ifndef __WINDOWS_
#include <windows.h>
#endif
#ifndef __TAPIDEF_H
#include "tapidef.h"
#endif
//
// function pointers to dynamically link the API
//
//
// TickerApi function pointer declarations
//
typedef int (WINAPI* pTApiInitialize)(int);
typedef void (WINAPI* pTApiShutDown)(void);
//
// ClientApi function pointer declarations
//
typedef int (WINAPI* pCApiInitialize)(int);
typedef void (WINAPI* pCApiShutDown)(void);
typedef void (WINAPI* pCApiSymbolRequest)(TfCApiSymbolRequest *pRequest);
typedef void (WINAPI* pCApiDbaseRequest)(TfCApiDbaseRequest *pRequest);
//
// ServerApi function pointer declarations
//
typedef int (WINAPI* pSApiInitialize)(char *, char *, char *, int, int);
typedef void (WINAPI* pSApiShutDown)(void);
typedef char * (WINAPI* pSApiGetLastError)(void);
__declspec(dllexport) int WINAPI TApiInitialize (int nMaxBufSize);
__declspec(dllexport) void WINAPI TApiShutDown (void);
