hashit is a generic hash library. hashit implements diverse collision handling methods. This function creates a hash table which is returned as a hash_t type. errno is set to ENOMEM if there wasnt enough memory avaliable for creating the table. Return value is a reference to the table just created or NULL when the table creation has failed. Parameters: - sizehint: Its used to give an aproximated desired value for the hash table, the function calculates the real size of the table using this parameter as a hint to the final value. - keysize: This is the size for the data type used as a key in the hash table. Keys are void *, so hashit needs to know how long they are. If key size is 0, is assumed that keys are strings. - hfunc: hfunc is a pointer to the hash function for the hash table. Typically you want to put here the value NULL to use the default hash function. Avaliable hash functions are BOB_HASH(Default) and ONEAT_HASH. You can add your own hash function if you know what are you doing. - cfunc: cfunc is the comparation function for the keys data. Semantics are the same that in strcmp function. The function should return 0 if both keys are equal, and a value different from zero if they are not. - flags: flags can have the following values: CHAIN_H: Hash table uses chaining for handling collisions OADDRESS_H: Hash table uses open address hashing for handling collisions OVERFLOW_H: Hasht table uses an overflow area for handling collisions If youre not sure about what collision handling your hash table should have, then use CHAIN_H. - int hashit_insert (hash_t htable, void *key, void *data) Whats New in This Release: - The build system was updated to the latest version of mobs. - This version is prepared to use pkg-config files, so hashit has now a .pc file included..
