This is a simple tool that dumps shared memory segments (System V and POSIX), files and text. It might be useful when you have to debug programs that use shared memory.

  • Dumps System V (shmget, shmat API) and POSIX (shm_open...) shared memory
  • Also dumps files (like cat) and text (like echo)
  • Several objects can be dumped in one run
  • Useful for debugging purposes
  • Works with Linux, FreeBSD and probably other un*x like systems
  • Comes with an optional utility to calculate System V IPC keys via the ftok(3) library function
