How can I end a function if found to be inValid?

I am writing this program and one of the functions is ifValid().
So ifValid is supposed to tell me whether there are too many X's or O's on a tic tac toe board. When i run the program it works, except for then it continues into the next function and then adds those print lines too.

How can I end this function if ifValid finds that the board is invalid?

Here is the code for this function:

Code:

bool ifValid(int topL, int topC, int topR, int cenL, int cenC,             int cenR, int botL, int botC, int botR)
{
   bool success = false;
   int total = 0;
   if (topL == 'X')
       total++;
   if (topC == 'X')
      total++;
   if (topR == 'X')
      total++;
   if (cenL == 'X')
      total++;
   if (cenC == 'X')
      total++;
   if (cenR == 'X')
      total++;
   if (botL == 'X')
      total++;
   if (botC == 'X')
      total++;
   if (botR == 'X')
      total++;


   if (total > 5)
      { 
      printf("Invalid Board.  There are too many X's.\n"); 
         
      }   
         
   else if(total <= 3)
      {
      printf("Invalid Board.  There are too many O's.\n");
      
      }
   (!success);
   return success; 
    }

Just stick a "return" right after the printf statements.
