+arguments: The first argument pCallback is a pointer to a callback function, we
+				   use it to reverse the final result. The second argument is a pointer of
+                   type void* used as a argument of function pCallback. The third argument
+                   piCount is a pointer of type int, an offset pointer, also be used as a argument
+                   of pCallback. The fourth argument is an integer of 32 bits, it indicates the buffer
+                   size pCallback uses.The fifth argument uNum is a decimal integer that will
+                   be converted to an integer in another radix. The sixth argument is used as
+                   base to conversion of number systems. The last argument indicates the integer
+                   after converted is a negative integer or not.
+return value: An integer, indicating if the function pCallback work successfully.
+note: The argument uNum should be a positive integer, after conversion of number systems
+		 the sign will be appended to string's tail.
