mark a file descriptor non-inheritable


#include <io.h>

void io_closeonexec(int64 fd);


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.
