Subject: Re: [Dev-C++] realloc =20

I tried to make an example reasigning to a so big block that it couldn't
be succeeding (I did  something like realloc(pointer,
15545454554545455454545454554545); but then windows closed the console,
and I couldn't see the result.=20

So, in the end, just what I feared at first, but couldn't prove the
second part with the experiment:=20
numbers =3D (int*)realloc(numbers, newsize); =20

=20
The casting is redundant (always speaking of C).

is a practice better to avoid. Because if it fails then you get a block
of memory which had been allocated , but not freed. =20

=20
For accuracy, if it fails you remain with the old allocated memory.

 so=20
if(!r){=20
[...]=20
free(p);=20
} =20
