Subject: sp3 simplification

I have now been convinced that using the double pointer in
deadlock unnecessarily muddies the water so I have changed
the prototype in the assignment spec:

int deadlock(
int numres,       // number of resource classes
int numproc,      // number of processes
int *avltab,      // pointer to the available table
int *reqtab,      // pointer to the requested table
int *alloctab,    // pointer to the allocated table
int *numdead,     // number of processes involved in deadlock
int *deadtab)     // id's of deadlocked processes
{

}

The way to pass a pointer to the 2-D array without generating
a warning is:

int dummy(
int *x)
{
   printf("%d", *(x + 2));
   return(0);
}

int tab[2][2] =
   {{1, 2,},
    {3, 4}};

int main()
{

   dummy(tab[0]);
   return(0);
}

The deadlock function could then access avltab[i][j] as:

   *(avltab + i * numres + j)
