Problem with sscanf

[hugues marty]

I'm having problem with sscanf. I would like to get items in a string
delimited by a coma. So I wrote :

sscanf("1,,3", "%[^,],%[^,],%[^,]", s1, s2, s3);

I get "1" into s1, "" into s2...
But what goes into s3 is *not* "3". Of course, I could write
my own function, but I would like to know if something is wrong
with this.

Tnx
