Re: [Boost-users] [Boost-Users][interprocess]ERROR_ACCESS_DENIED whenremoving a message_queue

It works fine, if my program does this : try { message_queue mq1(create_only, "toto", 10, 100); } catch (interprocess_exception &err) { return -1; }

message_queue::remove("toto");

but if it does : message_queue *mq1=0;

try { mq1 = new message_queue(create_only, "toto", 10, 100); } catch (interprocess_exception &err) { return -1; }

message_queue::remove("toto");

then the remove return ERROR_ACCESS_DENIED (on tthe DeleteFile call). I don't understand why. Is somebody can tell me what is wrong with my code ?

Just a wild guess: That's probably because the message queue is still open by the object mq1 points to. In the case where it works, mq1 is destroyed before the call to remove("toto").
