Hi All, Summary: Boost::bind() allocates memory on the heap. In my situaion it is necessary to use manual memory pool instead of heap allocation, to conform with real-time timing requirements. (no malloc() calls allowed in real-time code) A solution might be writing a custom allocator for the boost::bind()'s data, and use a pre-allocated memory pool with the "placement" new( void* ) to write directly into it. I've found that there was a discussion on std::allocator support for std::bind and std::function here: http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2308.html I'm not very familiar with the internals of bind() and Function in general, hence advice is appreciated. What is the status of boost::bind() and custom allocators? Is there a chance this could work? Am I missing some "easy" workaround or solution? Thanks for reading, -Harry
