.TH io_dontwantwrite 3
|
|
.SH NAME
|
|
io_dontwantwrite \- signal that you do not want to write to a descriptor
|
|
.SH SYNTAX
|
|
.B #include <libowfat/io.h>
|
|
|
|
void \fBio_dontwantwrite\fP(int64 fd);
|
|
.SH 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.
