+// The process pipe is used to notify the host about process exits,

+// (puid). This is for the purpose that the host  can clean up process resources
+// when a process is killed. It will fallback to the default path if the host
+// does not support it. Processes are identified by acquiring a per-process
+// 64bit unique ID (puid) from the host.

+// Calling processPipeInit will associate the current render thread with its
+// puid in the host.

+// This is called when creating rcEncoder.
