Rendezvous (Plan 9)Rendezvous is a synchronization mechanism in the Plan 9 operating system. It is a system call that allows two processes to exchange a single data item while synchronizing. Rendezvous call takes a tag and a value as its arguments. The tag is typically an address in memory shared by both processes. Calling rendezvous causes a process to sleep until a second rendezvous call with a matching tag occurs. Then, the values are exchanged and both processes are awakened. More complex syncronization mechanisms can be created from this primitive operation. See also mutual exclusion. External links
