Heap and stack differences (stack and heap)It is generally thought that in c it is divided into these storage areas1 stacks-with compiler auto-allocation release2 heap-typically released by programmers, if the programmer does not release, the program may end up being recycled by the OS3 Global zones (static zones), global variables and static variables are stored in a block, initialized global variables and static variables in an area, uninitialized global variables and uninitialized static vari
I have posted a post on the VMware Memory mechanism in Vmsky's forum (see this http://bbs.vmsky.com/thread-23285-1-2.html), and the last example is an account of the free memory tax (Idle Memory Tax, hereinafter referred to as IMT) in the case of memory allocation calculations, but unfortunately the guess of the algori

Before analyzing the virtual memory management, we should look at the specific allocation of Linux kernel memory. I started to be trapped in this place. The classification of kernel memory is not very clear. I extract one of the following:Kernel memory address============================================================

1. Run-time data area① program Counter Register is a small area of memory that can be thought of as the line number indicator of the byte code executed by the current thread if the thread is executing a Java method, Then this counter records the instruction address of the virtual machine bytecode that is executing if the native method is being executed, the value of this counter is empty (Undefined) This area is the only area in the Java virtual machi

Valgrind is a multi-purpose code profiling and memory debugging tool on x86 Linux. You can run your program in its environment to monitor memory usage, such as malloc and free in C language or new and delete in C ++. If you use uninitialized memory, set the memory outside the end of the array or forget to release the p
According to Windows core programming: The X86 operating system provides a maximum of 4 g of virtual memory per program, where 2G of virtual memory is provided to the system (specifically for what to investigate), and 2G of memory is left to the user. What's this 2G of memory going to do? First, you introduce the progr
