Can u explain what pairmake() function will do and what pairadd() function will do. What is the difference?

Have a look at src/lib/valuepair.c:

/* * Create a VALUE_PAIR from an ASCII attribute and value. */ VALUE_PAIR *pairmake(const char *attribute, const char *value, int operator)

/* * Add a pair at the end of a VALUE_PAIR list. */ void pairadd(VALUE_PAIR **first, VALUE_PAIR *add)

I'm sorry, but I can't explain it better than the comments already do. HTH, Enrik
