You're right, it really belongs in comp.lang.c, but here goes....

If you do not need the 256 byte arrays to be contiguous with each
other, you're much better off using "char *array[256]" and then
mallocing memory for each pointer.  If, for some reason, you do need
the arrays to be contiguous, then malloc a large block of memory (256
x 256) and assign array[x] = &foo[x*256] where 0 <= x < 256.

The reason you can not do what you want is that malloc returns a single
pointer.  You want malloc to return an array of pointers, which is not
it's purpose.

Oh yes, just to make this somewhat OS/2 relevant, does anyone know if
OS/2 2.0 is supposed to be 32 bit?  Can we get rid of "huge" arrays then?

P.S.  I've directed followups to comp.lang.c
