PROCESS_SET_INFORMATION
时间: 2024-04-14 17:24:24 浏览: 34
PROCESS_SET_INFORMATION是Windows操作系统中的一个访问权限,用于控制进程的设置信息。具体来说,它允许进程修改其自身的一些属性,例如进程的优先级、安全描述符等。这个权限通常只能由特权进程或具有适当权限的用户进行设置。
以下是一个使用PROCESS_SET_INFORMATION权限的示例代码,用于修改进程的优先级[^1]:
```python
import win32api
import win32con
import win32process
# 获取当前进程的句柄
current_process_handle = win32api.GetCurrentProcess()
# 修改进程的优先级为高
win32process.SetPriorityClass(current_process_handle, win32con.HIGH_PRIORITY_CLASS)
```
请注意,上述示例代码使用了Python的win32api、win32con和win32process模块,这些模块提供了与Windows API的交互功能。

你的代码存在如下bug:未定义标识符PROCESS_MEMORY_COUNTERS和GetProcessMemoryInfo
非常抱歉,您所指出的问题是由于我在代码中未添加必要的头文件所致,以下是修复后的代码:
```cpp
#include <iostream>
#include <windows.h>
#include <tlhelp32.h>
#include <psapi.h>
using namespace std;
int main() {
HANDLE hSnapshot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);
PROCESSENTRY32 pe32;
pe32.dwSize = sizeof(PROCESSENTRY32);
BOOL bMore = Process32First(hSnapshot, &pe32);
cout << "Process List:" << endl;
while (bMore) {
cout << "Process Name: " << pe32.szExeFile << endl;
cout << "PID: " << pe32.th32ProcessID << endl;
HANDLE hProcess = OpenProcess(PROCESS_QUERY_INFORMATION | PROCESS_VM_READ, FALSE, pe32.th32ProcessID);
if (hProcess) {
PROCESS_MEMORY_COUNTERS pmc;
if (GetProcessMemoryInfo(hProcess, &pmc, sizeof(pmc))) {
cout << "Working Set Size: " << pmc.WorkingSetSize / 1024 << "KB" << endl;
}
CloseHandle(hProcess);
}
bMore = Process32Next(hSnapshot, &pe32);
}
CloseHandle(hSnapshot);
return 0;
}
```
在代码中添加了 `psapi.h` 头文件,该头文件中定义了 `PROCESS_MEMORY_COUNTERS` 和 `GetProcessMemoryInfo`。这样就可以解决未定义标识符的问题了。感谢您指出代码中的漏洞!
macCannot set priority of nodemanager process 84282
As an AI language model, I do not have enough context to understand your question fully. However, based on the information you have provided, it seems like you are facing an issue with setting the priority of a nodemanager process with ID 84282 on a Mac computer.
Setting the priority of a process on a Mac can be done using the "renice" command. To set the priority of the nodemanager process with ID 84282, you can open the terminal and enter the following command:
renice -n [priority level] -p 84282
Replace [priority level] with the desired priority level, which can range from -20 (highest priority) to 20 (lowest priority).
If you are still unable to set the priority of the nodemanager process, it may be due to insufficient permissions. In this case, try running the command with sudo privileges:
sudo renice -n [priority level] -p 84282
If the issue persists, you may need to consult with a Mac expert or the nodemanager documentation for further assistance.
