| <Ralith> | miles: if uv_run knows that there are events to be processed, it will process them, and then there won't be events to process anymore. |
| 00:06:09
| <Ralith> | also, libuv does not 'sleep'; it blocks until there is work to do. |

| <Ralith> | if you are actualy in a realtime context, you should be using an RTOS, which can provide actual timing guarantees. |
| 00:09:48
| <Ralith> | from your mention of "frames" I speculate that you're actually just trying to write an interactive program, which is very different from hard realtime, and generally involves quite a lot of waiting |

| <miles> | Ralith: rdtsc is x86 specific, i have not much use of that |
| 02:02:44
| <miles> | are you implying, say i have for example 3 sockets ready, that if i use uv_run(loop, UV_RUN_NOWAIT) *once*, this one call will process at once all 3 sockets (basically calling a callabck three times), then return? |
| 02:03:01
| <miles> | if that's the case thats smarter than what i thought initially libuv was doing |

| <coderkevin> | So, I'm working on this custom stream LEP right now and have a few questions about the event loop, polling, and file descriptors. Anyone here able to field such questions? |
| 16:42:12
| <MLM> | Just ask, don't ask to ask |
| 16:42:49
| <coderkevin> | Well, considering the depth of some of the questions, I figured I'd be a little more polite than usual. |
| 16:44:32
| <coderkevin> | But here goes. With custom streams, I don't think we can assume all stream types boil down to file descriptors in the normal uniform way. Are there any other examples of streams implemented on a platform that don't use the traditional fd polling or iocp polling on windows, that i can use as a pattern? |
| 16:46:12
| <coderkevin> | Adding a generic stream polling call in uv_loop_run is a little more far-reaching than I had hoped for this implementation. I guess I'm looking for an alternative. |
| 16:47:22
| <coderkevin> | Any suggestions? |
| 16:51:26
| <coderkevin> | MLM: Did you get your windows build issues figured out? |
