You are attempting to link your project in such a way that the target of a relative addressing scheme is further away than can be supported with the 32-bit displacement of the chosen relative addressing mode. This could be because the current project is larger, because it is linking object files in a different order, … Read more
How do I determine the size of an object in Python? The answer, “Just use sys.getsizeof“, is not a complete answer. That answer does work for builtin objects directly, but it does not account for what those objects may contain, specifically, what types, such as custom objects, tuples, lists, dicts, and sets contain. They can contain instances each … Read more
I need to create a method of class that delete the instance. I want to know if there is any possible solution (even if it is not recommended) how to do this. Instance of this class will be stored in hundreds of different class. I will try to describe this, for example there will be … Read more
This looks wrong: Should probably be: (spaces added for convenience). EDIT: Some additional explanation: When you say return_data[i]=… you are trying to write something into return_data[i]. Now, return_data is char**, so return_data[i] is char*. So you are writing a pointer into some location in memory. It looks like your pointers are 8 bytes long (which is fine), but you’ve only allocated 6 bytes: MAX_SOURCE_STRING+1. So … Read more
Since we have a virtual address space of 2^32 and each page size is 2^12, we can store (2^32/2^12) = 2^20 pages. Since each entry into this page table has an address of size 4 bytes, then we have 2^20*4 = 4MB. So the page table takes up 4MB in memory.
No, you should not. “Hello world” is a constant string literal, you need to allocate memory using malloc() in C, or new in C++ if you want memory you are free to modify.
Your definition of a “conflict miss” is a bit unhelpful. A conflict miss occurs when a block is needed which existed in the cache before, but was evicted in favor of another block that had to be mapped to the same slot. In your example, the accesses to 13 and 25 are unique, so they … Read more
Softwares run on the OS on a very simple premise – they require memory. The device OS provides it in the form of RAM. The amount of memory required may vary – some softwares need huge memory, some require paltry memory. Most (if not all) users run multiple applications on the OS simultaneously, and given … Read more
The delete operator deallocates memory and calls the destructor for a single object created with new. The delete [] operator deallocates memory and calls destructors for an array of objects created with new []. Using delete on a pointer returned by new [] or delete [] on a pointer returned by new results in undefined … Read more
I have found the answer to my question myself:) So what I didn’t understand was how the glibc could differentiate between a Segfault and a corrupted double-linked list, because according to my understanding, from perspective of glibc they should look like the same thing. Because if I implement a double-linked list inside my program, how … Read more
