val post_add_hook : Netplex_types.controller -> unit

This function must be called from the post_add_hook of the component

val init : shm_wm:Plasma_shm.watermarks -> buf_wm:Plasma_shm.watermarks -> unit

This can be called from component context to set the low-water and high-water marks. By default, these marks are max_int, and shm_condition always returns `Normal.

When the sum of all allocated shared memory exceeds the high-water mark, the condition is switched to `Tight. It is switched back to `Normal when the sum sinks below the low-water mark.

It is not allocated more than max shared memory.
