NAME

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

SYNTAX

       #include <libowfat/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.
