int chprim_keycount(<geometry>geometry, int prim)
Returns the number of keys in a channel primitive.
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.
