Indeed. C doesn't actually have difference between pointer to some
data and arrays. You could use open array:
procedure Decompose(var A: array of double);
Or you could use
procedure Decompose(A: pdouble);
That way it would be precisely the same as the C solution. You can
array-index A the same way as in C(in some fpc modes)
I would only do that when mixing C and Pascal code, to interface with C
code.
In a Pascal-only program, never. Converting bad C code (that means
almost any C code)
to good FPC code is a great thing to do, converting to bad FPC code is
not as much fun.
