3d array as function argument

Question

I have a function which takes a 2d-array as an argument. Then I have a 3d-array e.g. temp[5][100][100]. I want to pass the 2d portion of this array to the function. How can I do this?

int inteference_sets(int array[][],int array_size,int max_channel){
     //function codes
}
int main(){
    int k;

    int temp[5][100][100];
    for(k=1;k<=4;k++){
       interference_sets(temp[k], , ) //this is how the program intends to work
    }
 }

Is it possible? If yes, then how?

By "second portion" I assume you mean any of the five 100x100 partitions, by reference/address. — WhozCraig

#define DIM1 100
#define DIM2 100

int inteference_sets(int (*array)[DIM2], int array_size, int max_channel)
{
     int row, col;

     for( row = 0; row < array_size; row++ )
     {
         for( col = 0; col < DIM2; col++ )
         {
             int value = array[row][col];
             //function codes
         }
     }
} 

int main()
{
    int k;

    int temp[5][DIM1][DIM2];

    for(k=1;k<=4;k++)
    {
       interference_sets(temp[k], DIM1, ) //this is how the program intends to work
    }
 }

+1. Also note that unlike C++, almost all reasonable intelligent C implementations support VLAs (variable length arrays) including VLA parameters. This allows you to specify at runtime what the compiler would normally require constants to deduce. See it live for an example. Nice answer.
