you mean the function qsort() in crt?
here is a sample

struct foostruct{
int key;
int value1;
 int value2;
};

int compare(const void* a1, const void* a2){
return ((foostruct*)a1)-key - ((const foostruct*)a2)-key;
}

void bar(){
foostruct s[] ={ {3, 2, 3}, {5, 2, 1}, {2, 6, 5} };
qsort(s, sizeof(s)/sizeof(s[0]), sizeof(s[0]), compare);
}

Thank U!
