Date: 2015may29 OS: Linux Q. Linux: Where can I find an introduction to inter-process communication (IPC) on Linux? A. Beej has a terrific guide for Unix-like IPC: http://beej.us/guide/bgipc/ It however omits POSIX IPC. POSIX has some advantages. - Like the discussed methods works on all Unix/Linux's - Its newer than SysV so has some improvements - Its thread-safe - Its available on more platforms More info: http://stackoverflow.com/questions/4582968/system-v-ipc-vs-posix-ipc Also Dbus which is Linux-specific is not mentioned.
