Library for Shared Buffer IPC

libshbuf implements a new kind of IPC the “shared buffer”, a faster, more flexible replacement for standard Unix FIFOs. It offers the following advantages

  • Normally better latency and throughput
  • Full access to the buffer at any time
  • Connecting processes need not to be children of each other
  • Arbitrary buffer lengths
  • Memory mapped
  • “Backlog”

The implementation is based on SysV shared memory, semaphores and message queues. It makes use of POSIX pthreads.
