Hi,

The compiler gives me:

I think, the memset arguments should be swapped:

diff --git a/config.c b/config.c
index 94f6845..53beb4b 100644
--- a/config.c
+++ b/config.c
@@ -69,7 +69,7 @@ cSatCableNumbers::cSatCableNumbers(int Size, const char *s)
{
size = Size;
array = MALLOC(int, size);
- memset(array, size * sizeof(int), 0);
+ memset(array, 0, size * sizeof(int));
FromString(s);
}

Ville Skyttä already reported this to me and I have removed that call
altogether for the next developer version, because the array is initialized
explicitly, anyway.

 Fine! :-)

Lars.
