Hi
Our application has the following scenario using Boost V1.0.52:
1) Process A writes to boost interprocess shared memory. The files appear at C:\ProgramData\boost_interprocess\...
2) Process A launches Process B
3) Process B attempts to read from shared memory but fails. It is attempting to read from: C:\Users\<username>\AppData\Local\Temp\boost_interprocess\...
This failure only occurs on one single Windows 8 64 bit machine out of many we have tested. On all other machines, the application works perfectly.
If you look in boost/interprocess/detail/tmp_dir_helpers.hpp: #if defined (BOOST_INTERPROCESS_WINDOWS) winapi::get_shared_documents_folder(tmp_name); if(tmp_name.empty() || !winapi::is_directory(tmp_name.c_str())){ tmp_name = get_temporary_path(); } #else if shared documents folder is not found, then the temporary path is used. The shared documents folder is found in the registry in the following key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders\Common AppData Hope it helps, Ion
