I can't find them. I have had a look at the docs. For example, libs/spirit/doc/scanner.html has the following code snippet: template< typename IteratorT = char const*, typename PoliciesT = scanner_policies<> > class scanner; The problem is in the html sources where every line is folloowed by a blank line, e.g.: <html> <head> <title>The Scanner and Parsing</title> ... -- this seems to be a problem with the HTML code generator.

bjam docs for boost developers?
by Jeremy Siek 29 Jan '04

29 Jan '04

Hi All, Are there bjam docs for boost developers that explain how to write a Jamfile in the style of the Jamfiles in the existing boost libraries? I already know about: http://www.boost.org/tools/build/jam_src/index.html but that doesn't cover stuff like "run" and "compile" and "link-fail". -Jeremy ------------------------------------------------------------------------ ----------------- Jeremy Siek http://php.indiana.edu/~jsiek/ Ph.D. Student, Indiana Univ.

Perhaps not a poll > method but I'm not much interested in the low-end solutions anyway. Small point. Please don't knock the pollster ;-) Polling trades CPU for latency gain. Polling is a high end solution for low latency requirements, which covers a lot of my issues (not the psychological ones though ;-)). Not so good for high throughput systems, but it can be. A combined approach, poll for a while you can then wait for an interrupt ( a bit like spin-locks ), can be especially beneficial for supercomputer oriented frameworks as plenty of research shows. A polling, single threaded architecture is often best for the style of performance oriented apps I develop. I have also seen some neat SAN software developed with polling that wouldn't have otherwise worked at all well. Regards, Matt Hurd.

Index.html for 1.31.0 and spirit
by Russell Hind 29 Jan '04

29 Jan '04

Is the index.html complete for 1.31.0? I think something could be mentioned for spirit as to what version it is now, and also the fact that it nolonger supports bcc32 compilers just to give people a warning that they are best to stick with 1.30.2 if they use spirit and borland compilers. (Or replace the spirit directory with the one from 1.30.2) Cheers Russell

I have been off for a few days now, and I like to see that I have arrived at the very same conclusions than you. 1) I believe now that most likely everything can be done with boost.thread as is (question still is performance) 2) I used an approach as 1 thread / WFMO instead beeing able to directly wait on condvars _and_ IO simulateneously. (Altough this approach isn't easily portable, as it contains a lot of platform dependencies. Also this approach does not scale very well for the multiplexing case since WMFO/select scenarios are limited in the number of waitable things. This is where IO completion should enter the scene.) 3) I agree that the real question should be whether there should be a such an IO library in boost. Personally I would vote for such a thing, perhaps based on already existing "C" async_io libs, much like the pthreads lib. If anyone is interseted I could try to post my files, but I am not sure where I should post them since they are more a bit of example appliaction code than library code. Would the boost files area be adequate? Roland

Ok, I think I got those fixed. Also, I fixed the bad figure references in adjacency_list.html and adjacency_matrix.html.
