Where's the code?  I couldn't find closefrom outside any packages here:

Is the one in the DLL (a Windows library) what I'm looking for?

Is closefrom only intended for closing files read from or also for files
open for write operations?  I.e., does this statement

date from before the introduction of closefrom?
