to customize the behaviour. The macros are:
[[give_hashfn]]
-- `HASH_GIVE_HASHFN` -- the table will use `uns
+- `HASH_GIVE_HASHFN` -- the table will use `uint
HASH_PREFIX(hash)(key)` to calculate hash of `key`.
There is a sensible default for integers and strings.
In the case of <<key_complex,`HASH_KEY_COMPLEX`>>, it is mandatory
*)` is used to initialize the rest of node. Useful if you use
<<fun_HASH_PREFIX_OPEN_PAREN_lookup_CLOSE_PAREN_,`HASH_PREFIX(lookup())`>>
- `HASH_GIVE_ALLOC` -- you need to provide `void
- \*HASH_PREFIX(alloc)(uns size` and `void HASH_PREFIX(free)(void \*)`
+ \*HASH_PREFIX(alloc)(uint size` and `void HASH_PREFIX(free)(void \*)`
to allocate and deallocate the nodes. Default uses
- <<memory:xmalloc()>> and <<memory:xfree()>>, <<mempool:mempool
+ <<basics:xmalloc()>> and <<basics:xfree()>>, <<mempool:mempool
routines>> or <<eltpool:eltpool routines>>, depending on
<<use_pool,`HASH_USE_POOL`>>, <<auto_pool,`HASH_AUTO_POOL`>>,
<<use_eltpool,`HASH_USE_ELTPOOL`>> and <<auto_eltpool,`HASH_AUTO_ELTPOOL`>> switches.
- <<table_alloc:`HASH_GIVE_TABLE_ALLOC`>> -- you need to provide `void
- \*HASH_PREFIX(table_alloc)(uns size` and `void HASH_PREFIX(table_free)(void \*)`
+ \*HASH_PREFIX(table_alloc)(uint size` and `void HASH_PREFIX(table_free)(void \*)`
to allocate and deallocate the table itself. Default uses
- <<memory:xmalloc()>> and <<memory:xfree()>> or the functions
+ <<basics:xmalloc()>> and <<basics:xfree()>> or the functions
from `HASH_GIVE_ALLOC` depending on <<table_alloc:`HASH_TABLE_ALLOC`>> switch.
[[params]]
- `HASH_ZERO_FILL` -- initialize new nodes to all zeroes.
[[table-alloc]]
- `HASH_TABLE_ALLOC` -- allocate the table the same way as nodes. If
- not provided, <<mempory:xmalloc()>> is used.
+ not provided, <<basics:xmalloc()>> is used.
- `HASH_TABLE_GROWING` -- never decrease the size of allocated table of nodes.
[[table_dynamic]]
- `HASH_TABLE_DYNAMIC` -- By default, only one global hash table is
of `HASH_PREFIX(table) *` structure. It can be useful in combination
with <<table_dynamic:`HASH_TABLE_DYNAMIC`>> to access per-table custom variables
from macros or function switches before you include the generator.
+[[lookup_detect_new]]
+- `HASH_LOOKUP_DETECT_NEW` -- the prototype for lookup is changed to `node *lookup(key, int *new_item)`,
+ `new_item` must not be NULL and returns 1 whether lookup just created a new item in the hashtable
+ or 0 otherwise.
