Rick,
I didn't know whether you meant returning the array as the function value, or
simply as an argument to/from the function.  Assuming the latter:

int main ( void )
{
  int  myArray[MAXSIZE];
  int  nElems;
  ...
  ...
  myFunction( myArray,&nElems );
  ...
}

void myFunction ( int array[], int *nelems )
{
  ...
  use the 'array'
  ...
  return;
}

Yours, Geoff Houck
