如何解析/proc/pid/cmdline [英] How to parse /proc/pid/cmdline

问题描述

我正在尝试在Linux上拆分进程的cm​​dline，但看来我不能依靠它用'\ 0'字符分隔.您知道为什么有时使用'\ 0'字符作为分隔符，有时使用常规空格吗?

I'm trying to split the cmdline of a process on Linux but it seems I cannot rely on it to be separated by '\0' characters. Do you know why sometimes the '\0' character is used as separator and sometimes it is a regular space?

您知道检索可执行文件名称及其路径的任何其他方法吗?我一直在尝试使用"ps"获取此信息，但是它总是返回完整的命令行，并且可执行文件名被截断.

Do you know any other ways of retrieving the executable name and the path to it? I have been trying to get this information with 'ps' but it always returns the full command line and the executable name is truncated.

谢谢.
