> The best solution is, I believe, to validate the request at> read-time instead of open-time.Be very careful that you don't do if(request_valid(x)) { memcpy_tofs(....)as the paging of the process could sleep and cause the data to be copiedfrom the new task I think. It might need if(request_valid(x)) { memcpy_tofs(....) if(!request_valid(x)) memset(..,0,...) }Alan
