NAME
       io_closeonexec - mark a file descriptor non-inheritable

SYNTAX
       #include <io.h>

       void io_closeonexec(int64 fd);

DESCRIPTION
       io_closeonexec marks a file descriptor non-inheritable.  It will be
       automatically closed if the process executes a different one.  The
       descriptor will not be automatically closed when you fork() a new child
       process, though.
