获取进程的memory地址的值并修改

Question

我试图模仿 Cheat Engine 在 mac os 上的操作，从值中获取 memory 地址并对其进行修改。 到目前为止，我已经这样做了：

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <stdint.h>


#include <libproc.h>
#include <mach/mach_init.h>

// Get array of all process ids
uint32_t* get_pids(uint16_t* size) {
    uint32_t number_of_pids = proc_listpids(1, 0, NULL, 0);
    uint32_t* buffer = malloc(sizeof(uint32_t) * number_of_pids);
    uint8_t return_code = proc_listpids(1, 0, buffer, sizeof(buffer) * number_of_pids);
    uint16_t sum = 0;
    for(int i = 0; i < number_of_pids; i++) {
        if(buffer[i] != 0) {
            sum++;
        }
    }
    uint32_t* final = malloc(sizeof(uint32_t) * sum);
    for(int i = 0, t = 0; i < number_of_pids; i++) {
        if(buffer[i]) {
            final[t++] = buffer[i];
        }
    }
    *size = sum;
    return final;
}
int main() {
    uint16_t size;
    uint32_t* pids = get_pids(&size);
    uint16_t maxpathlength = 1024;
    uint16_t path_size = maxpathlength * 4;
    char path_buffer[path_size];

    uint32_t pid = 0;
    for(int i = 0; i < size; i++) {
        memset(path_buffer, '\0', sizeof(path_buffer));
        uint8_t return_code = proc_pidpath(pids[i], path_buffer, path_size);
        if(strstr(path_buffer, "Geometry Dash")) {
            pid = pids[i];
        }
        //printf("PID: %d, Process: %s\n", pids[i], path_buffer);

    }
    mach_port_name_t port = 0;
    if(task_for_pid(mach_task_self(), pid, &port)) {
        printf("Run as root!\n");
    }
    printf("%d\n", port);
    return 0;
}

所以我到了那里，现在有了目标 pid 的 mach 端口，但是我不确定从这里到 go 的位置，因为我在mach_vm方法上找到了几乎 0 个好的文档，而且我尝试的任何东西都失败了。 我应该如何 go 这样做？
