NAME
       io_dontwantwrite - signal that you do not want to write to a descriptor

SYNTAX
       #include <io.h>

       void io_dontwantwrite(int64 fd);

DESCRIPTION
       io_dontwantwrite	 tells the next io_wait() that you don't want to write
       to this descriptor for now.  Call io_wantwrite() again  if  you	change
       your mind.

       You  have  to  have  called  io_fd on the descriptor first (io_pipe and
       io_socketpair do this for you).	Waiting on descriptors only works  for
       sockets,	 fifos	and  pipes.  It may also work on devices and TTYs, but
       that is platform dependent -- you should not rely on that.
