Comment (by annakrat):

Are you sure? I don't see anything like that in the code. It must be an
integer, but it is not really used there.

Comment (by martinl):

From first look it seems to me that the module supports two modes:
coordinates and categories, see
source:grass/trunk/vector/v.net.path/path.c#L141

OK, now I understand better your ticket. The 'id' is stored in created
attribute table, source:grass/trunk/vector/v.net.path/path.c#L100. Why do
you think that it should be a layer?

> OK, now I understand better your ticket. The 'id' is stored in created
attribute table, source:grass/trunk/vector/v.net.path/path.c#L100. Why do
you think that it should be a layer?

ID is correct, it is the ID of the path to be created. Layers are defined
with the arc_layer, node_layer, turn_layer, and turn_cat_layer options.
Several paths can be created at once, e.g. with

{{{
1 1 2
2 2 3
3 3 4
}}}
using the syntax "id start_point_category end_point_category". The output
will contain three different paths. You can then display a single path
with d.vect where="id = 1" etc. Closing as invalid.
