void*heap_caps_malloc(size_tsize,uint32_tcaps ){returnNULL; } Is this function deprecated? what is flash_mock.cpp? In the heap_caps.c I have also found the real heap_caps_malloc function declaration: Code:Select all IRAM_ATTRvoid*heap_caps_malloc(size_tsize,uint32_tcaps){void* ptr...

`heap_caps_malloc` 函数允许你为分配的内存块指定一组能力(capabilities)。这些能力定义了该内存块可以执行的操作,例如读、写、执行等。这使得内存分配具有更高的安全性和灵活性。 函数的原型通常如下: ```c void* heap_caps_malloc(size_t size, uint64_t capabilities); ``` 参数解释: 1. `size`:要分...
