@1@ Sorts the given array pointed to by in ascending order. The array contains elements of  bytes. Function pointed to by is used for object comparison. @2@ Same as, except that the additional context parameter is passed to  and that the following errors are detected at runtime and call the currently installed constraint handler function:
 * or is greater than rsize_max
 * or is a null pointer (unless  is zero)

If indicates two elements as equivalent, their order in the resulting sorted array is unspecified.

Return value
@1@ (none) @2@ zero on success, non-zero if a runtime constraints violation was detected
