Error in qsort function in Programming Pearls?
- by Dervin Thunk
Hello, is it just me or this code in Programming Pearls is wrong (quicksort wants 2 const voids, no?) If so, is my solution right? Apologies, just learning...
int wordncmp(char *p, char* q)
{ int n = k;
for ( ; *p == *q; p++, q++)
if (*p == 0 && --n == 0)
return 0;
return *p - *q;
}
int sortcmp(char **p, char **q)
{ return wordncmp(*p, *q);
}
...
qsort(word, nword, sizeof(word[0]), sortcmp);
Is this a solution?
int sortcmp(const void *p, const void *q)
{ return wordncmp(* (char * const *) p, * (char * const *) q);
}
