lv_mem.h

lv_mem_init

Initialize to use malloc/free/realloc etc

void lv_mem_init(void)

lv_mem_deinit

Drop all dynamically allocated memory and reset the memory pools' state

void lv_mem_deinit(void)

lv_mem_add_pool

lv_mem_pool_t lv_mem_add_pool(void *mem, size_t bytes)

lv_mem_remove_pool

void lv_mem_remove_pool(lv_mem_pool_t pool)

lv_malloc

Allocate memory dynamically

void * lv_malloc(size_t size)

Returns: void * — pointer to allocated uninitialized memory, or NULL on failure

lv_calloc

Allocate a block of zeroed memory dynamically

void * lv_calloc(size_t num, size_t size)

Returns: void * — pointer to allocated zeroed memory, or NULL on failure

lv_zalloc

Allocate zeroed memory dynamically

void * lv_zalloc(size_t size)

Returns: void * — pointer to allocated zeroed memory, or NULL on failure

lv_malloc_zeroed

Allocate zeroed memory dynamically

void * lv_malloc_zeroed(size_t size)

Returns: void * — pointer to allocated zeroed memory, or NULL on failure

lv_free

Free an allocated data

void lv_free(void *data)

lv_realloc

Reallocate a memory with a new size. The old content will be kept.

void * lv_realloc(void *data_p, size_t new_size)

Returns: void * — pointer to the new memory, NULL on failure

lv_reallocf

Reallocate a memory with a new size. The old content will be kept. In case of failure, the old pointer is free'd.

void * lv_reallocf(void *data_p, size_t new_size)

Returns: void * — pointer to the new memory, NULL on failure

lv_malloc_core

Used internally to execute a plain malloc operation

void * lv_malloc_core(size_t size)

lv_free_core

Used internally to execute a plain free operation

void lv_free_core(void *p)

lv_realloc_core

Used internally to execute a plain realloc operation

void * lv_realloc_core(void *p, size_t new_size)

lv_mem_monitor_core

Used internally by lv_mem_monitor() to gather LVGL heap state information.

void lv_mem_monitor_core(lv_mem_monitor_t *mon_p)

lv_mem_test_core

lv_result_t lv_mem_test_core(void)

lv_mem_test

Tests the memory allocation system by allocating and freeing a block of memory.

lv_result_t lv_mem_test(void)

Returns: lv_result_t — LV_RESULT_OK if the memory allocation system is working properly, or LV_RESULT_INVALID if there is an error.

lv_mem_monitor

Give information about the work memory of dynamic allocation

void lv_mem_monitor(lv_mem_monitor_t *mon_p)
