I'm trying to retrive fd count for my process by `proc_pidinfo(...,PROC_PIDLISTFDS,...)`, it works in [C demo](https://github.com/palominolabs/get_process_handles/), but rust code does not. Finally, I found the problem. I think correct `PROC_PIDLISTFDS` value is 1, not 2. This is where I found it define. ``` bogon:include zhangli.pear$ pwd /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include bogon:include zhangli.pear$ rg PROC_PIDLISTFDS sys/proc_info.h 656:#define PROC_PIDLISTFDS 1 ```
