IltmmWMProfile::get_MutualExclusionCount Example for C

For complete code, refer to the CNVWM demo. The example below checks all the streams for a mutual object. If the quality is less than 50, it is removed.

LPTSTR OLE2A(LPCOLESTR lpw) 
{ 
   static CHAR convert[512]; 
   if(!lpw) 
      return NULL; 
   convert[0] = '\0'; 
   WideCharToMultiByte(CP_ACP, 0, lpw, -1, convert, 512, NULL, NULL); 
   return convert; 
} 
void IltmmWMProfile_get_MutualExclusionCount_Example (IltmmWMProfile *pProfile) 
{ 
   IltmmWMMutualExclusion *pMutualExc = NULL; 
   IltmmWMStreamConfig *pStreamConfig = NULL; 
   long lMCount; 
   long lSCount; 
   long lStreamNumber; 
   long lQuality; 
   BSTR bstrData; 
   char strUpdate[255]; 
   int i; 
   int j; 
   IltmmWMProfile_get_MutualExclusionCount(pProfile, &lMCount); 
   // iterate through the objects 
   for(i=0; i<lMCount; i++) 
   { 
      IltmmWMProfile_GetMutualExclusion(pProfile, i, &pMutualExc); 
      IltmmWMMutualExclusion_get_StreamCount(pMutualExc, &lSCount); 
      if(lSCount == 0) 
      { 
         IltmmWMProfile_RemoveMutualExclusion(pProfile, pMutualExc); 
         IltmmWMMutualExclusion_Release(pMutualExc); 
      } 
      else 
      { 
         for(j=0; j<lSCount; j++) 
         { 
            // obtain the stream number 
            IltmmWMMutualExclusion_GetStream(pMutualExc, j, &lStreamNumber); 
            // get the stream using it's number 
            IltmmWMProfile_GetStreamByNumber (pProfile, lStreamNumber, &pStreamConfig); 
            // check it's quality, if it is less than 50, remove it... 
            IltmmWMStreamConfig_get_Quality(pStreamConfig, &lQuality); 
            if(lQuality < 50) 
            { 
               // remove it... 
               IltmmWMMutualExclusion_RemoveStream(pMutualExc, lStreamNumber); 
            } 
            // report the user with update... 
            IltmmWMMutualExclusion_get_Type(pMutualExc, &bstrData); 
            sprintf(strUpdate, "Updating Mutual object with type :\n %s", OLE2A(bstrData)); 
            SysFreeString(bstrData); 
            MessageBox(NULL, strUpdate, "Update...", MB_OK); 
            IltmmWMStreamConfig_Release(pStreamConfig); 
            IltmmWMMutualExclusion_Release(pMutualExc); 
         }
