Users are expected -to implement their own hashing. - -Data Structures ---------------- - -`struct hash_table`:: - - The hash table structure. The `array` member points to the hash table - entries. The `size` member counts the total number of valid and invalid - entries in the table. The `nr` member keeps track of the number of - valid entries. - -`struct hash_table_entry`:: - - An opaque structure representing an entry in the hash table. The `hash` - member is the entry's hash key and the `ptr` member is the entry's - value. - -Functions ---------- - -`init_hash`:: - - Initialize the hash table. - -`free_hash`:: - - Release memory associated with the hash table. - -`insert_hash`:: - - Insert a pointer into the hash table. If an entry with that hash - already exists, a pointer to the existing entry's value is returned. - Otherwise NULL is returned. This allows callers to implement - chaining, etc. - -`lookup_hash`:: - - Lookup an entry in the hash table. If an entry with that hash exists - the entry's value is returned. Otherwise NULL is returned. - -`for_each_hash`:: - - Call a function for each entry in the hash table. The function is - expected to take the entry's value as its only argument and return an - int. If the function returns a negative int the loop is aborted - immediately. Otherwise, the return value is accumulated and the sum - returned upon completion of the loop. |
