Title: Building a win32 TAPI application
Post by: misgana on November 11, 2010, 06:53:13 AM

  Hello , I was planning to develope a TAPI application,and i downloaded small code from msdn,then i added the uuid.lib to my linker and tapi3.dll ;but my small code failed at compile time.please is there anyone that could  help me with my problem?
#include<tapi.h>
#include<windows.h>

int main(){
// Initialize COM.
HRESULT hr = CoInitializeEx(
     NULL,
     COINIT_MULTITHREADED
     );
// If (hr != S_OK) process the error here. 

// Create a TAPI entry point object.
ITTAPI *gpTapi;    // globally allocated
hr = CoCreateInstance(
     CLSID_TAPI,
     NULL,
     CLSCTX_INPROC_SERVER,
     IID_ITTAPI,
     (LPVOID *)&gpTapi
     );
// If (hr != S_OK) process the error here. 

// Initialize TAPI.
hr = gpTapi->Initialize();
// If (hr != S_OK) process the error here.

   return 0;
}

To compile you need the include "tapi3.h" which is not present in PellesC distribution. You can get it from msdn downloading the last SDK.
