| int flextcp_context_wait | ( | struct flextcp_context * | ctx, |

Waits for events for up to timeout_ms milliseconds. Is not guaranteed to block, but only does so when flextcp_context_canwait returns 0.

| void flextcp_context_waitclear | ( | struct flextcp_context * | ctx | ) |
Clear events off of waitfd after waking up. Does not process any events any events, just reads the count off the internal eventfd.

| int flextcp_context_waitfd | ( | struct flextcp_context * | ctx | ) |
Get file descriptor for waiting on events in this context. Note that blocking is only allowed after flextcp_context_canwait indicates this. After waking up, canwait has to be called again before blocking again.
