.SH NAME

io_timeouted \- return a file descriptor over deadline

.SH DESCRIPTION
|
|
io_timeouted returns the next file descriptor that is past it's deadline.
|
|
If no descriptors are past their deadlines, it returns -1.
|
|
|
|
After io_timeouted() returned -1, you should wait a second before
|
|
calling it again. Checking for connections past their deadline involves
|
|
walking through the whole data structure, which may thrash the CPU
|
|
cache needlessly. Treat it as an expensive operation.
