Hello, It seems to me that the static function bool remove(const char * name) in class boost::interprocess::shared_memory_object returns false when it should return true and vice versa. The documentation on boost interprocess says: "The remove operation might fail returning false if the shared memory does not exist, the file is open or the file is still memory mapped by other processes" However, the following simple test program for example prints "should not print" on Windows XP 64. I'm compiling with MSVC 2008 and using boost 1.41.0. /* Test program */ #include #include <iostream> int main(int argc, char* argv[]) { using namespace boost::interprocess; using namespace std; { shared_memory_object shm(open_or_create, "foo", read_write); } if(shared_memory_object::remove("foo")) cout << "should print" << endl; if(shared_memory_object::remove("foo")) cout << "should not print" << endl; return 0; } /* Test program ends */ Am I interpreting the documentation correctly? Regards, Jarno
