Macros

#define wmem_new(allocator, type)
 Allocate memory sufficient to hold one object of the given type.
#define wmem_safe_mult_type_size(type, num)
 Overflow-safe multiplication of the size of a type by a number of items.
#define wmem_alloc_array(allocator, type, num)
 Allocate memory sufficient to hold n objects of the given type.
#define wmem_new0(allocator, type)
 Allocate memory sufficient to hold one object of the given type. Initializes the allocated memory with zeroes.
#define wmem_alloc0_array(allocator, type, num)
 Allocate memory sufficient to hold n objects of the given type. Initializes the allocated memory with zeroes.

Typedefs

Functions

WS_WARN_UNUSED WS_DLL_PUBLIC void * wmem_alloc (wmem_allocator_t *allocator, const size_t size) G_GNUC_MALLOC G_GNUC_ALLOC_SIZE(2)
 Allocate the requested amount of memory in the given pool.
WS_WARN_UNUSED WS_DLL_PUBLIC void * wmem_alloc0 (wmem_allocator_t *allocator, const size_t size) G_GNUC_MALLOC G_GNUC_ALLOC_SIZE(2)
 Allocate the requested amount of memory in the given pool. Initializes the allocated memory with zeroes.
WS_DLL_PUBLIC void wmem_free (wmem_allocator_t *allocator, void *ptr)
 Returns the allocated memory to the allocator.
WS_WARN_UNUSED WS_DLL_PUBLIC void * wmem_realloc (wmem_allocator_t *allocator, void *ptr, const size_t size) G_GNUC_ALLOC_SIZE(3)
 Resizes a block of memory, potentially moving it if resizing it in place is not possible.
WS_DLL_PUBLIC void wmem_free_all (wmem_allocator_t *allocator)
 Frees all the memory allocated in a pool.
WS_DLL_PUBLIC void wmem_gc (wmem_allocator_t *allocator)
 Triggers a garbage-collection in the allocator.
WS_DLL_PUBLIC void wmem_destroy_allocator (wmem_allocator_t *allocator)
 Destroy the given allocator, freeing all memory allocated in it.
WS_DLL_PUBLIC wmem_allocator_twmem_allocator_new (const wmem_allocator_type_t type)
 Create a new allocator of the given type.
WS_DLL_PUBLIC void wmem_init (void)
 Initialize the wmem subsystem.
WS_DLL_PUBLIC void wmem_cleanup (void)
 Teardown the wmem subsystem.
WS_DLL_PUBLIC void wmem_enter_scope (wmem_allocator_t *allocator)
 Mark an allocator as entering a scoped memory region.
WS_DLL_PUBLIC void wmem_leave_scope (wmem_allocator_t *allocator)
 Exit a scoped memory region and free all scoped allocations.
WS_DLL_PUBLIC bool wmem_in_scope (wmem_allocator_t *allocator)
 Check whether an allocator is currently in a scoped region.
