[GRASS-dev] Updating categories

[Roberto Antolin]

Hello all,
Just a question: How can I update the category line of a vector map?
I'm trying with "Vect_rewrite_line()" and the same line_number and 
line_points, and the new line_cats,
but I don't like this function because I want to keep the same line_number.
Did you understand me? Any suggestion?

Thank you,
Roberto Antolin.
