I declare a sort routine (like qsort(3)) as
extern void
sort (
void *array_to_sort,
int number_of_items_in_the_array,
int size_of_items_in_the_array,
int (*comparison_function) (void *, void*));
Then, I create a comparison function that takes not "void *" but
"void const *".
int
cmp_const (
void const *a,
void const *b)
{
...
}
My dpANS compiler (gcc) emits a warning:
a.c: In function main:
a.c:65: warning: argument passing between incompatible pointer types
Removing the two `const's from the comparison function causes the
compile to go smoothly.
Is this a bug or a feature? Of gcc or of dpANS? If this is a
feature, why is it a feature?
