SYNOPSIS

       #include "SDL3/SDL.h"

       void SDL_qsort(void *base, size_t nmemb, size_t size, SDL_CompareCallback compare);

DESCRIPTION

       For example:

              typedef struct {
                  int key;
                  const char *string;
              } data;

              int SDLCALL compare(const void *a, const void *b)
              {
                  const data *A = (const data *)a;
                  const data *B = (const data *)b;

                  if (A->n < B->n) {
                      return -1;
                  } else if (B->n < A->n) {
                      return 1;
                  } else {
                      return 0;
                  }
              }

              data values[] = {
                  { 3, "third" }, { 1, "first" }, { 2, "second" }
              };

              SDL_qsort(values, SDL_arraysize(values), sizeof(values[0]), compare);
