io_close(3)           DragonFly Library Functions Manual           io_close(3)

NAME
       io_close - close a file descriptor

SYNTAX
       #include <io.h>

       void io_close(int64 fd);

DESCRIPTION
       io_close eliminates the descriptor numbered fd. This usually does not
       mean eliminating the object that the descriptor is talking to.  (For
       example, if a descriptor writes to a named disk file, closing the
       descriptor will not remove the file; it simply removes one way of
       writing to the file. On the other hand, a pipe disappears as soon as no
       descriptors refer to it.)

       io_close has no return value; it always succeeds in deallocating the
       memory used for the descriptor.  If fd is not the number of a
       descriptor, io_close has no effect.

       io_close() is like close(), but it also removes the descriptor from the
       internal io_wait() data structures.  If you called io_fd on a
       descriptor, you need to use io_close to close it, not just close().
