* @brief A compatible implementation of the GNU C Library (Glibc) qsort_r.
*
* Sorts an array using the quicksort algorithm. This function is thread-safe
* by allowing a custom context pointer (arg) to be passed to the comparison
* function.
*
* @param base A pointer to the first element of the array to be sorted.
* @param nel The number of elements in the array.
* @param width The size in bytes of each element in the array.
* @param compare The comparison function, which takes two elements and a context
* pointer. The function must return:
* - A negative integer if the first element is less than the second.
* - Zero if the elements are equal.
* - A positive integer if the first element is greater than the second.
* @param arg The custom pointer passed to the comparison function.
