[Vala] Function to sort a list of strings?

Hi all,

I use the following, straightforward code to sort a List<string>:


That works fine, but when I invoke valac (v0.13.1 or 0.12) to compile the
program, I get a warning:

warning: passing argument 2 of ‘g_list_sort’ from incompatible pointer type
/usr/include/glib-2.0/glib/glist.h:103:10: note: expected ‘GCompareFunc’ but
argument is of type ‘int (*)(const char *, const char *)’

Since the sorting itself works fine, I'm not unduly worried, but I still
wonder what's the cause of the warning. Should I use some other function
instead of strcmp to sort list of strings? If so, which one?

Best regards
