I've got an issue that I can't figure out....  It has to do with a 
compiler warning:

warning: passing arg 3 of `scandir' from incompatible pointer type

Now scandir is declared in dirent.h:

extern int scandir (__const char *__restrict __dir,
                     struct dirent ***__restrict __namelist,
                     int (*__selector) (__const struct dirent *),
                     int (*__cmp) (__const void *, __const void *));

I am calling it as follows:

n = scandir ("/data/pictures", &namelist, ysfilter, alphasort);

and my 3rd argument (ysfilter) is declared as follows:

int ysfilter (struct dirent *dir);

The 4th argument is

extern int alphasort (__const void *__e1, __const void *__e2)
      __THROW __attribute_pure__;

so they should be both the same....

I must be blind....  Or I'm missing something really obvious.

Why am I getting a warning?

missing const here.

DUH!  Thanks.  I got so focused on the function type that I didn't check
the args....
