memory

问题 I try to read memory at address of a process that's the code : std::cout << "Found Process " << procEntry32.szExeFile << " With process ID " << procEntry32.th32ProcessID << std::endl; hProc == OpenProcess(PROCESS_ALL_ACCESS, FALSE, procEntry32.th32ProcessID); pID = procEntry32.th32ProcessID; if (hProc == NULL) { std::cout << "failed getting handle" << std::endl; } CloseHandle(hProcSnap); std::cout << "hProcSnap handle closed ... " << std::endl; return true; Code Output I use DWORD64 This code

问题 Through /proc file system , it's probable to read memory mappings with /proc/PID_PROCESS/maps , but is there any native APIs that dedicated for this function in C/C++ ? i.e to find out memory address that are writable and readable for process with PID 9322: %> awk -F "-| " '$3 ~ /rw/ { print $1 " " $2}' /proc/9322/maps 0804e000 0804f000 085ed000 0860e000 b7707000 b7708000 b7864000 b7865000 b7865000 b7868000 b7897000 b7898000 b78b6000 b78b7000 bfd2e000 bfd50000 And those address are passed

问题 can i set “MemorySwap” and “MemorySwappiness” for docker service? I would like to disable memory swap for docker containers (started by docker service) but i don’t want to disable it for host machine. What means value of -1 at “MemorySwappiness”? Docker version: 17.06.2-ce 回答1: Although this question is old, as it has no answer I have decided to post one. Indeed, disabling memory swap is now supported by just using the option --memory-swap when creating the container. You simply have to set -

It cannot possibly do so, because that memory may not even have come from malloc() . You can free() the memory any time after calling

问题 I asked the same problem two times (see here Getting segmentation fault while using malloc ) and improved my code. But I am unable to allocate memory for larger value of m and n . The heart of my code is : #include<stdio.h> #include<stdlib.h> int main() { int i,j,n,m,p = 0 ; int sum[100000] = {0}; scanf("%d%d%d",&n,&m,&p); /*for ( i = 0 ; i < n ; i++ ) { for( j = 0 ; j < m ; j++ ) { a[i][j] = j + 1 ; } }*/ int **a = malloc( n * sizeof *a ); for(i=0; i<n; i++) { a[i] = malloc( m * sizeof **a);

问题 I'm new to c++ after learning basic Object Oriented Programming in Java so I'm having a difficult time grasping memory deallocation. The assignment was to create a Weighted Directed Graph... I'm getting the error: "terminate called after throwing an instance of 'std::bad_alloc' what(): std::bad_alloc" when I run certain inputs through my code, and I'm having a difficult time figuring out what is causing it. I googled the error and found that it was a memory problem, so I attempted to go

问题 I want use task_for_pid() and attach to another process and then change its memory on iOS system. I could do it successfully on OS X with the help of authorization services API, but on iOS, task_for_pid() always returns KERN_FAILURE . I need to get task_for_pid() function to work on jailbreak iPhone under root. As discussed in “Authentication” iOS does not provide this API, What should I do? Could I run as root on iOS Simulator and how to test app required running as root? 回答1: It is
