Code examples

The following code example fails the check and will give a warning:

#include <stdlib.h>

int values[] = { 40, 10, 100, 90, 20, 25 };

int compare (const void * a, const void * b)
{
  return ( *(int*)a - *(int*)b );
}

int main ()
{
  qsort (values, 6, sizeof(int), compare);
  return 0;
}

The following code example passes the check and will not give a warning about this issue:

#include <stdlib.h>

int values[] = { 40, 10, 100, 90, 20, 25 };

int compare (const void * a, const void * b)
{
  return ( *(int*)a - *(int*)b );
}

int main ()
{
  return 0;
}
