- Synopsis:
- $close(<file descriptor>)
-
- Technical:
- This function unbinds the given file descriptor (previously returned by
- the $open() function) from the underlying file, causing the file to be
- committed to disk if necessary. An error is returned if it is passed a
- file descriptor not produced by an $open() call.
-
- Practical:
- This function is used to close a file that was opened for reading or
- writing by $open(). Data corruption may result if the client exits
- before all open files are closed.
-
- Returns:
- -1 error
- 0 file closed successfully
-
- See Also:
- open(6); read(6); write(6)
