The moderating force is currently discussing the question of membership visibility, and the poll is, at least for now, off. Suggestions and comments can (of course) be sent to the moderators or to the list. Bjorn [Non-text portions of this message have been removed]

New poll for Boost-Users
by Boost-Users＠yahoogroups.com 10 Jan '02

10 Jan '02

Enter your vote today! A new poll has been created for the Boost-Users group: Yahoo! groups can be configured so that only the moderators can view membership list, or so that membership lists can be viewed by anyone (email addresses are always munged for non-moderators; my email address would appear as something like jim.hyslop@.le...) Do you want the membership list to be freely available to be viewed by anyone, or do you want the membership list kept private so only the moderators can view the list? o I want only the moderators to be able to view the membership list o I want anyone to be able to view the membership list To vote, please visit the following web page: http://groups.yahoo.com/group/Boost-Users/polls Note: Please do not reply to this message. Poll votes are not collected via email. To vote, you must go to the Yahoo! Groups web site listed above. Thanks!

Jon, can we lighten that restriction slightly, to "limited" (Moderators can create polls, members can vote)? -- Jim

Because that's the way the group was set up. Only moderators can view the membership list. It can be changed easily enough, if people want it changed.

boost::pool + shared memory
by Tom Matelich 07 Jan '02

07 Jan '02

I need to build a system for having miscellaneous objects in a shared memory segment. Essentially, we need a few inter-process singletons. These classes have STL containers, so I was looking at using pool_allocator and writing a UserAllocator to use ACE_Mem_Map ( http://doc.ece.uci.edu/Doxygen/Current/html/ace/classACE__Mem__Map.html#_det ails ) or something. I just wanted to see if anyone had done anything resembling this and could give me any pointers or tips. Thanks, Tom Matelich PS Why can't I see who is a member of this group? I wanted to check to see if Steve Cleary was a member. Sorry if you are Steve.

overflow of clock_t with clock(), timing longer processes
by gigu74 07 Jan '02

07 Jan '02

hello hackers first a hi to everyone. just signed today as a new member to this mailinglist. well.. i've got a problem and hope someone can help me. i run a c++ program (mostly on a sunblade 100 or a sunblade 1000) about genetic algorithms which takes quite some time to solve for certain problems (up to 100 hours) because its important to me to compare different jobs i need to measure the elapsed cpu time used for the particular jobs. well, i could use the standart system time, but because my running job is not always the only one i dont get really worthy results. so i used the std::clock(). but measuring 1/1000000 of a seconds with that and with the clock_t beeing a long int of course this results in a overflow after around 36 minutes. thought to find something about that in the boost library but timer.hpp just gets also de maximum elapsed time out.. doesnt really help is there some way this can be achieved? would be really neat to get an answer from anyone soon. thanks uf

bind question
by Duane Murphy 05 Jan '02

05 Jan '02

Is there a syntax for making boost::bind bind to functions that are templates? Here is an (extremally simplified) example that doesnt compile: #include <boost/bind.hpp> template < class Function > void f( Function func ) { func( 46 ); } void g( int num ) { num++; } int main( void ) { boost::bind( f, g )(); boost::bind( f, _1 )( g ); return 0; } The two bind lines in main both get an error "call of non-function". Is there a way to make this work? ..Duane p.s. CodeWarrior 7 on a Macintosh (OS X)

Another Bind Question
by Duane Murphy 04 Jan '02

04 Jan '02

Bind has been working very well for some of the things I have been wanting to do. I have run into a rather puzzling problem this time and was wondering what was happening: Here is the example: void f( int ) { } struct array_obj { int operator[]( int ){ return NULL; } }; int main() { array_obj a; int array[1]; int value = a[0]; boost::bind( f, _1 )( 3 ); boost::bind( f, _1 )( value ); boost::bind( f, _1 )( array[0] ); boost::bind( f, _1 )( a[0] ); return 0; } The first three bind statements compile just fine. The third one issues an error: function call 'operator()(int)' does not match. Along with all 20 variations of operator() generated by bind. Obviously there is something amiss with going through the return value of operator[](). I also get the same problem using an iterator which would be going through operator*(). I am using CodeWarrior 7 on Mac on OS X. Could this be a compiler specific problem? I can work around the problem using bind1st but it seems odd that bind1st works and bind doesnt? Could CW have included some magic in bind1st to work around this? Thanks for the help, ..Duane

Using boost::thread under Visual C++
