   • What is the difference between using malloc to allocate memory to a struct pointer and pointing a struct pointer to a struct's memory address?

     Top Answer

     Answered Oct 14, 2016 · 1 votes

     There are several differences here:

     • With malloc you can repeat the call multiple times, and get new valid memory area for your struct; there is only one statically allocated struct
     • Memory obtained through malloc needs to be freed at the end; statically allocated memory does not need freeing
     • Statically allocated struct is visible from multiple functions inside the translation unit; memory from malloc is not shared with other functions unless you pass a pointer to them explicitly.

   • What is the difference between an OutOfMemoryError and a memory leak

     Top Answer

     Answered Sep 06, 2022 · 11 votes

     A memory leak in Java is when objects you aren't using cannot be garbage collected because you still have a reference to them somewhere.

     An OutOfMemoryError is thrown when there is no memory left to allocate new objects. This can be caused by a memory leak, but can also happen if you're just trying to hold too much data in memory at once.

     The JDK includes useful tools like jhat and visualVM that allow you to inspect the objects in memory and the references between them. Using these you can often find the objects that are causing the problem.

     Example

     Here is a particularly silly memory leak. The old objects are never used, but cannot be garbage collected. While it may seem ridiculous, you can easily create an equivalent leak by mistake in large projects.

     public class Leaky{ private static List<Object> neverRead = new ArrayList<Object>(); public static void main(String[] args) { while(true) { neverRead.add(new Object()); } }}-

     This one is not a memory leak, but will usually cause an OutOfMemoryError somewhere.

     public class Allocaty{ public static void main(String[] args) { long[] array = new long[Integer.MAX_VALUE]; long value = 1L; for(int ii=Integer.MAX_VALUE; ii>=0; ii--) { array[ii] = value++; } String str = Arrays.toString(array); System.out.printf("%d: %s", array.length, str); }}-

   • What is the difference between writing to a file and a mapped memory?

     Top Answer

     Answered Sep 02, 2011 · 15 votes

     A memory mapped file is actually partially or wholly mapped in memory (RAM), whereas a file you write to would be written to memory and then flushed to disk. A memory mapped file is taken from disk and placed into memory explicitly for reading and/or writing. It stays there until you unmap it.

     Access to disk is slower, so when you've written to a file, it will be flushed to disk and no longer reside in RAM, which means, that next time you need the file, you might be going to get it from disk (slow), whereas in memory mapped files, you know the file is in RAM and you can have faster access to it then when it's on disk.

     Also, mememory mapped files are often used as an IPC mechanism, so two or more processes can easily share the same file and read/write to it. (using necessary sycnh mechanisms)

     When you need to read a file often, and this file is quite large, it can be advantageous to map it into memory so that you have faster access to it then having to go open it and get it from disk each time.

     EDIT:

     That depends on your needs, when you have a file that will need to be accessed very frequently by different threads, then I'm not sure that memory mapping the file will necessarily be a good idea, from the view that, you'll need to synch access to this mmap'ed file if you wish it write to it, in the same places from different threads. If that happens very often, it could be a spot for resource contention.

     Just reading from the file, then this might be a good solution, cause you don't really need to synch access, if you're only reading from it from multiple threads. The moment you start writing, you do have to use synch mechanisms.

     I suggest, that you have each thread do it's own file access in a thread local way, if you have to write to the file, just like you do with any other file. In this way it reduces the need for thread synchronization and the likelyhood of bugs hard to find and debug.

   • what is the difference between Malloc and new operator to allocate a memory?

     Top Answer

     Answered Jul 15, 2010 · 4 votes

     In C++ you should always use new and pair it with delete.

     • It calls constructor(s) for the object(s).
     • Since it is an operator, it can be overloaded.
     • It throws exceptions, but there is an exceptionless version.
     • There is a "placement new", which allows you to put your object in already allocated memory.

     What is the difference between a dangling pointer and memory leak?

     You could say a dangling pointer is the opposite of a memory leak.

     One is a pointer that doesn't point to valid memory, and one is valid memory that nothing points to.

     (But as the other answers point out, your code is neither.)

   What is memory reclaim?

   • Memory reclaim is the mechanism of creating more free RAM pages, by throwing somewhere else the data residing in them. It has nothing to do with files. When more RAM is needed, data is dropped from RAM (trashed away, if it can be refetched) or copied to the swap file (so the data will be refetchable).

   How does a memory reclaim function work?

   • It reclaims memory by copying live objects from one memory space to another, effectively compacting memory and reclaiming unused space. The memory space is divided into two equal-sized regions: the $from-space$ and the $to-space$.

   What is the difference between RAM and cache memory?

   • While both RAM and cache are volatile memory, they have different uses. RAM typically stores the data required by programs in use on your computer, while cache memory stores frequently used program instructions or the specific data a CPU requires next. When people talk about RAM, they're usually talking about Synchronous Dynamic RAM (SDRAM).
