Example of writing CSV using StrTk String Toolkit Library

I just started to learn the String Toolkit Library. I've read the CodeProject article, but it seemed focused on parsing and tokenization. Can someone point me to an example of using it to serialize a struct array to CSV file? For example, given:

typedef struct {
    int x;
    int y;
} Point;

I'd like to write an array of Points to a csv file, one point per row. The int to string conversion should be fast.
