.TH io_dontwantread 3
|
|
.SH NAME
|
|
io_dontwantread \- signal that you do not want to read from a descriptor
|
|
.SH SYNTAX
|
|
.B #include <io.h>
|
|
|
|
void \fBio_dontwantread\fP(int64 fd);
|
|
.SH 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_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.
