ruby memory allocation

One: Memory allocation method 5 kinds stack :is the store of variables that are allocated by the compiler when needed and automatically purged when not needed. The variables inside are usually local variables, function parameters, and so on. In a process, the user stack at the top of the user's virtual address space is compiled with it to implement the function invocation. heap :is the

In the Linux memory allocation mechanism, the first use of physical memory, when the physical memory is idle (enough), does not release its memory consumption, even if the memory-hogging program has been shut down, the program occ

sentence is: In the stack memory is stored in a pointer to a heap of memory p. The program will first determine the size of the memory allocated in the heap, then call operator new to allocate memory, and then return the first address of the memory, put in the stack, his as

The following is a detailed analysis of the differences between the stack area and the heap area memory allocation, the need for friends can come to the referencehas always been the understanding of this problem is hazy, I believe a lot of friends are also like this, always hear the memory will be allocated on the stack, one will be allocated on the heap, then wh

Dynamic memory allocation is most commonly used to allocate an array of some type. We can use arrays to handle a lot of data, but in many cases we don't know how many elements this array will have, so it's a good idea to think about how much of an array to define when you define an array. For example, we have to analyze the number of inputs and get all the positive numbers to be stored in an array for his u

When we understand some of the fundamentals of the. NET framework, it is really necessary to understand some of the underlying knowledge. For example, how the. NET Framework is memory-managed, how it is garbage collected ... In this way, we can write more high-performance programs. In the. NET Framework, there are 2 places for us to save management data: One is "heap", also called "Managed Heap", managed by the. NET Framework's garbage collector (gar

Commonly used data stores:In the C language, the memory space is divided into three zones depending on the time (lifetime) in which the data exists in memory:1. Program Area: the code used to store the program, that is, the binary code of the program;2. static storage: for storing global variables and static variables, the space of these variables has been allocated at the time of program compilation;3. Dyn

Introduction: The elements of an array are stored in contiguous locations in memory. When an array is declared. The memory it needs is allocated at compile time.However, we can use dynamic memory allocation to allocate memory for it at execution time.The life cycle of a piec

obtain new memory space, the function first tries to find the available memory space from the internal heap, if there is no memory space available, then attempts to use the system to dynamically increase the size of the program data segment memory, the newly allocated space is first organized into the internal heap, I

1. Memory allocation mode There are three ways to allocate memory: [1] is assigned from a static storage area. The memory is allocated when the program is compiled, and exists throughout the running of the program. such as global variables, static variables. [2] created on the stack. When the function is executed, t
