Functions

register(Name, Pid, Site)

Register a Pid under Name. Name can be any erlang term.

register_name(Name, Pid)
send(Name, Msg)
spawn_link_md(Fun)

Spawn a new process using proc_lib and copy the logger metadata from the calling process to the new process.

spawn_md(Fun)

Spawn a new process using proc_lib and copy the logger metadata from the calling process to the new process.

spawn_md_opt(Fun, SpawnOpts)

Spawn a new process using proc_lib and copy the logger metadata from the calling process to the new process. Pass options to proc_lib for spawning the process.

unregister(Name, Site)

Unregister the current process.

unregister_name(Name)
whereis(Name, Site)

Lookup the pid of the process.
