In other words, the cost of process spawning is proportional to the size of the ar-guments that spawn has to copy. Se hela listan på medium.com Erlang is designed for massive concurrency. Erlang processes are light-weight (grow and shrink dynamically) with small memory footprint, fast to create and terminate and the scheduling overhead is low. 12.2 Process Creation. A process is created by calling spawn: Thus erlang:hibernate/3 will never return to its caller. If the process has any message in its message queue, the process will be awaken immediately in the same way as described above.

Extracts the initial call of a process that was started using one of the spawn or start functions in this module. Process can either be a pid, an integer tuple (from which a pid can be created), or the process information of a process Pid fetched through an erlang:process_info (Pid) function call. Returns the process identifier of the current Erlang emulator in the format most commonly used by the OS environment. Returns Value as a string containing the (usually) numerical identifier for a process.
