io_dontwantread(3)	    Library Functions Manual	      io_dontwantread(3)

NAME
     io_dontwantread - signal that you do not want to read from a descriptor

SYNTAX
     #include <libowfat/io.h>

     void io_dontwantread(int64 fd);

DESCRIPTION
     io_dontwantread  tells  the next io_wait() that you don't want to read from
     this descriptor for now.  Call io_wantread() again if you change your mind.

     You have to have called io_fd on the descriptor first (io_pipe and io_sock-
     etpair 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 plat-
     form dependent -- you should not rely on that.

SEE ALSO
     io_wait(3), io_canread(3), io_wantread(3), io_fd(3)
