Question

当我尝试使用下面的代码进行编译时，我收到以下错误。我不知道如何解决它。我用Google搜索了。也问其他人，但没有人能够帮助我。通过theos在mac上编译。如果有人可以帮助我，我将非常感激。

错误输出

error: assigning to
  'kern_return_t' (aka 'int') from incompatible type 'uint *'
  (aka 'unsigned int *')
err = reinterpret_cast<uint *>(address* sizeof(data));

代码

bool writeData(vm_address_t address,  string str) {

//declaring variables

kern_return_t err = 0;
mach_port_t port = mach_task_self();

size_t find = str.find("0x");

if (find != -1) {

    str.replace(find, 2, "");
}

int len = str.size();

 char data[len / 2];

int x = 0;

for(int i = 0; i < len; i += 2) {

    string dat = str.substr(i, 2);
    uint8_t tmp;
    sscanf(dat.c_str(), "%hhx", &tmp);
    data[x] = tmp;
    x++;

}

//set memory protections to allow us writing code there

err = vm_protect(port, (vm_address_t)address, sizeof(data), NO, VM_PROT_READ | VM_PROT_WRITE | VM_PROT_COPY);

//check if the protection fails

if (err != KERN_SUCCESS)
    return FALSE;

//write code to memory

err = reinterpret_cast<uint64_t *>(address* sizeof(data));

if (err != KERN_SUCCESS)
    return FALSE;

//set the protections back to normal so the app can access this address as usual

err = vm_protect(port, (vm_address_t)address, sizeof(data), NO, VM_PROT_READ | VM_PROT_EXECUTE);

if (err != KERN_SUCCESS)
    return FALSE;

return TRUE;

}

遇到kern_return_t错误的问题
