io_eagain(3) Library Functions Manual io_eagain(3) NAME io_eagain - tell io_wait that you got an EAGAIN SYNTAX #include <libowfat/io.h> void io_eagain(int64 fd); DESCRIPTION If io_wait() said that you can read from a descriptor, you try to read from it, and you get EAGAIN, you need to tell io_wait(). This is im- portant for edge triggered event notification schemes like Linux 2.4's SIGIO, or you will lose events. io_tryread(), io_trywrite() and io_sendfile() and iob_send() already take care of this for you. This function is only of interest if you integrate io_wait() with legacy code that uses read/write directly. SEE ALSO io_wait(3) io_eagain(3)
