float chprim_eval(<geometry>geometry, int prim, float time)
Returns the evaluated value of the channel primitive at the given time.
geohandle
A handle to the geometry to write to. Currently the only valid value is 0
or geoself, which means the current geometry in a node. (This argument may be used in the future to allow writing to other geometries.)
prim
The primitive number of the channel primitive to evaluate.
time
The time in seconds at which to evaluate.
