I'm no CPP expert, but benchmark-wise, wouldn't this call make us get the file twice? Is there a CPP way to achieve this same result?

I haven't find an effective way to acquire stat in cpp way directly to avoid this dilemma, it would be great if anyone could help, and this will only affect efficiency when using skipSymlinkDir to skip symbolic link dirs.

#49255 would implement a more general solution (provision of a filtering function to limit traversal). |

skipSymlinkDiroption to thefs.readdirto allow for behavior similar to thefind [path] -printandfind -L [path] -printcommands. This option would control whether symbolic link directories are skipped or traversed during directory listing.fs.readdir([path], {withFileTypes: false})andfs.readdir([path], {withFileTypes: true})Refs: #51858
