io_close(3)io_close(3)NAMEio_close - close a file descriptor
SYNTAX
#include <io.h>
void io_close(int64 fd);
DESCRIPTIONio_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 writ‐
ing 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 descrip‐
tor, 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 descrip‐
tor, you need to use io_close to close it, not just close().
