Names and NameSet Operations

A name set is a set of unique names (i.e. - no duplicates). These sets are used in conjunction with the on_synch_diff_cb callback function.

rht_name_cmp is a comparison function for rht_name. It performs a strncmp on the two strings.

rht_nset_size returns the number of names in a name set.

rht_nset_contains returns true (non-zero) if the name set nset contains the name name, or false (zero) otherwise.

rht_nset_get_it performs a lookup of name in nset and initializes it to reference the name if found, or a special "end" entry if not. The function returns it.

rht_nset_begin initializes it to reference the first name in nset or the special "end" entry if the set is empty.

rht_nset_end initializes it to reference the special "end" entry of nset.

rht_nset_it_val returns a pointer to the name that it is referencing.

rht_nset_it_eq compares two name set iterators for equality and returns true (non-zero) if they are referencing the same position in the same set and false (zero) otherwise.

rht_nset_it_next advances it to reference the next entry in the name set nset. It is illegal to call rht_nset_it_next on the special "end" entry of a name set.
