Glad to help! .....but,sincerely your comment is not completely clear: a small explanation of what you don't understand would be really appreciated ;-) Just have a look at boost::bind and tell us what is not clear.

i'm not a computer scientist and so not an expert of programming stuff: i read the documentation but is not clear (at least for me). i'd like to understand what this function does and how i can use it for my purposes

(i have to declare n subscriber (with a for cycle for instance) that writes the data in a vector (of size n)...so i have to pass an integer to the same callback to increment the position in the vector

my problem is explained better here: http://answers.ros.org/question/64747/write-in-a-vector-through-the-same-ros-callback-using-boostbind-c/
