How to return the RGB values of the current Pixel i stop on it by the mouse cursor??

My Code:

#include <opencv\cv.h>
#include <opencv\highgui.h>
#include <iostream>

void mouseEvent(int evt, int x, int y, int flags, void* param){
    evt==CV_EVENT_MOUSEMOVE;
    printf("Current Position: x= %d y= %d\n",x,y);
}

int main() 
{
cvNamedWindow("rgb"); 
CvCapture*capture =cvCaptureFromCAM(0);
IplImage* rgb ;

while(1){
rgb= cvQueryFrame( capture ); 
cvShowImage("rgb",rgb);
cvSetMouseCallback("rgb",  mouseEvent, 0);



char c = cvWaitKey(33);
if( c == 27 ) break;
}

cvReleaseCapture( &capture );
cvDestroyWindow( "rgb" );

}
