问题描述
我想在我正在编写的工具中监控给定的进程。 用户可以选择一个可执行文件，并且该工具应该能够判断该进程何时开始和结束。
我能够（在某种程度上）实现这一目标的唯一方法是使用 QProcess 偶尔使用过滤器运行任务列表，但这需要大量工作，而且实际上不是解决方案。
有没有什么好的方法可以实现这一点，尤其是不必经常检查正在运行的进程？
编辑：
尝试编译 Microsoft 文档中的示例时，我收到以下错误：
error: cast from pointer to smaller type 'DWORD' (aka 'unsigned long') loses information
error: cast from 'BYTE*' {aka 'unsigned char*'} to 'DWORD' {aka 'long unsigned int'} loses precision [-fpermissive]
_tprintf( TEXT("\n Base address = 0x%08X"),(DWORD) me32.modBaseAddr );
