Define a 2D array and pass it in a function

[casybay]

Hi all,

I would like to ask for you help to correct the following code for me. I am trying to define a 2D int array, then pass it in a function. I got an error "error: a value of type "void *" cannot be used to "xx file", line 113". Here is my code:

   .......
    void fun(int**);
......
///////////////////////////////
   int main(int argc, char** argv){
.......
    //the following is line 113
    int **distance = malloc(n*sizeof(int *)),**trace = malloc(n*sizeof(int *));
    distance = trace = malloc(n * sizeof(int *));
    for (i = 0; i < m; i++) {
        distance[i] = trace[i] = malloc(m * sizeof(int));
     }
.......
    fun(distance);
   }
//////////////////////////////
  void fun(int **distance){
.....
         for(int i=0;i<n;i++){
            for(int j=0;j<m;j++){
               distance[i][j]=distance[i][j]*2;
           } 
        }
......
   }
//////////////////////////////

Thx!!!!
