| int lh_table_delete | ( | struct lh_table * | t, |
| void * | k | ||
| ) |
Delete a record from the table. If a callback free function is provided then it is called for the for the item being deleted.
- Parameters
-
t the table to delete from. k a pointer to the key to delete.
- Returns
- 0 if the item was deleted.
- -1 if it was not found.
Definition at line 211 of file linkhash.c.
Delete a record from the table. If a callback free function is provided then it is called for the for the item being deleted.
- Parameters
-
t the table to delete from. e a pointer to the entry to delete.
- Returns
- 0 if the item was deleted.
- -1 if it was not found.
Definition at line 182 of file linkhash.c.
| void lh_table_free | ( | struct lh_table * | t | ) |
Free a linkhash table. If a callback free function is provided then it is called for all entries in the table.
- Parameters
-
t table to free.
Definition at line 111 of file linkhash.c.
| int lh_table_insert | ( | struct lh_table * | t, |
| void * | k, | ||
| void * | v | ||
| ) |
Insert a record into the table.
- Parameters
-
t the table to insert into. k a pointer to the key to insert. v a pointer to the value to insert.
Definition at line 124 of file linkhash.c.
| void* lh_table_lookup | ( | struct lh_table * | t, |
| void * | k | ||
| ) |
Lookup a record into the table
- Parameters
-
t the table to lookup k a pointer to the key to lookup
- Returns
- a pointer to the found value or NULL if it does not exist.
Definition at line 174 of file linkhash.c.
Lookup a record into the table.
- Parameters
-
t the table to lookup k a pointer to the key to lookup
- Returns
- a pointer to the record structure of the value or NULL if it does not exist.

| char * | name, | ||
| lh_entry_free_fn * | free_fn, | ||
| lh_hash_fn * | hash_fn, | ||
| lh_equal_fn * | equal_fn | ||
| ) |
Create a new linkhash table.
- Parameters
-
size initial table size. The table is automatically resized although this incurs a performance penalty. name the table name. free_fn callback function used to free memory for entries when lh_table_free or lh_table_delete is called. If NULL is provided, then memory for keys and values must be freed by the caller. hash_fn function used to hash keys. 2 standard ones are defined: lh_ptr_hash and lh_char_hash for hashing pointer values and C strings respectively. equal_fn comparison function to compare keys. 2 standard ones defined: lh_ptr_hash and lh_char_hash for comparing pointer values and C strings respectively.
- Returns
- a pointer onto the linkhash table.
