In the Boost::Interprocess documentation and under the heading "Where is this being allocated?"; is an example of how to create a vector of strings in a managed_shared_memory segment. Link to Boost::Interprocess documentation here: http://www.boost.org/doc/libs/1_53_0/doc/html/interprocess/allocators_contai ners.html#interprocess.allocators_containers.containers_explained Please could this example be extended to demonstrate; 1. How to add string elements to the shared memory vector from a different process? 2. How to access and copy strings from the shared memory vector from a different process? This really would be invaluable to people trying to use Boost::Interprocess for the first time! My particular project has ground to a halt for over a month simply trying to get a working implementation of a Boost::Interprocess mutex synchronised shared memory vector of strings. I would like one process to add strings to the shared memory vector and several other processes to read string data from the vector. Right now I don't know if I'll ever get it to work! Running out of ideas here! Hope someone can help. Thanks, Riskybiz.
