Summary

Declaration

Definition

from esp_cache_private.h:82

__attribute__((deprecated("Use 'heap_caps_calloc' with MALLOC_CAP_CACHE_ALIGNED caps instead"))) esp_err_t esp_cache_aligned_calloc(size_t n, size_t size, uint32_t heap_caps, void **out_ptr, size_t *actual_size);

Implemented in esp_cache.c:215

Arguments

Argument

Description

n

Number of continuing chunks of memory to allocate

size

Size of one chunk, in bytes

heap_caps

Flags, see `MALLOC_CAP_x`

out_ptr

A pointer to the memory allocated successfully

actual_size

Actual size for allocation in bytes, when the size you specified doesn't meet the cache alignment requirements, this value might be bigger than the size you specified. Set null if you don't care this value.

Return value

- ESP_OK: - ESP_ERR_INVALID_ARG: Invalid argument - ESP_ERR_NO_MEM: No enough memory for allocation

Notes

Now only support 'MALLOC_CAP_INTERNAL', 'MALLOC_CAP_DMA' and 'MALLOC_CAP_SPIRAM'
