Thread: Worksafe Array of Strings

Hi

I want to have a list of thousands of strings as one array.
Last time I used to do:

Code:

char *InternW[] =
{
"string1",
"string2",
"string3",
...
}

but on rare occasions enumerating all strings gave me wrong output, so now I think this method is just as unsafe as

Code:

char buf[largenumber];

I came up with a large list of realloc()ing the array buffer and appending the string to it - where I came into trouble with the pointers =/

But is there a safe way of doing that? It's a standard console program, can it have resources, so the strings are saved as standalone binary data in the executable? I don't want to use a txt datafile because I want a sole exe.

Thanks in advance, Hawk

The way to get strings as standalone binary data in the executable is to do this:

Code:

const char *InternW[] =
{

    "string1", "string2", "string3", ...

}

This gives you an array of pointers to where those strings live in memory. I don't know what "wrong output" you were getting; the usual culprit is trying to change these strings, which you can't.

I see
Will I be able to store millions of bytes without any problems this way?

Provided you have millions of bytes of RAM; most people do, these days. There's probably a limit on how large an array could be, but I would guess it's rather large; the size of the stack, divided by four or so, since the array is storing pointers and not the strings themselves (I can't find a listed minimum in the standard).

Thanks, it seems to work just fine
I'll post if I find the limit
