I'm trying to return a pointer to an array from a function and then
using it in my main program
I'm missing something really fundamental here...
i.e.

int* myFunc(...)
{
    // int m_Array[...] is member of some class
    for (int i = 0; i < SOME_NUMBER; i++)
         m_Array[i] = i;
    return m_Array;
}
I also tried casting the m_Array to int*

The compiler error is coming from trying to index the returned pointer
as if it were
an array name.

int* pArray = myFunc(...)
int nFirstInt = pArray[0];

This gives me the error.
I haven't tried indexing the returned pointer using pointer arithmetic
yet.  I wanted to see if
this is possible.  I thought it was but I guess I was wrong.  Aren't
array names also pointers to first element of the array?  I looked in
the DJGPP archives and this exact compiler problem was discussed but the
context was passing arrays *to* functions.  Any help with this would be
greatly appreciated.
