iob_addfile_close - add file region to I/O batch

#include <iob.h>

int iob_addfile_close(io_batch* b,int64 fd,uint64 off,uint64 n);

iob_addfile_close schedules n bytes from the file descriptor fd starting at offset off to be written with the I/O batch b.

You may not close fd before iob_send indicates it is done.

iob_reset will call io_close(fd).

Returns 1 on success, 0 on failure. In the failure case, the file descriptor has been closed.
