有没有办法监视 C++/MacOS 中的堆使用情况？

#include<iostream>
#include<malloc/malloc.h>

int main() {
    malloc_statistics_t stats = {0};
    malloc_zone_statistics(NULL, &stats);

    std::cout << "Blocks allocated: "<< stats.blocks_allocated<< std::endl;
    std::cout << "Blocks deallocated: "<< stats.blocks_deallocated<< std::endl;
    std::cout << "Blocks in use: "<< stats.blocks_in_use<< std::endl;
    std::cout << "Bytes allocated: "<< stats.bytes_allocated<< std::endl;
    std::cout << "Bytes deallocated: "<< stats.bytes_deallocated<< std::endl;
    std::cout << "Bytes in use: "<< stats.bytes_in_use<< std::endl;

    return 0;
}
