我该如何提供一个重载以获取矢量参数？

void res(uint8_t* buffer, int len) 
{ 
std::vector<uint8_t> buf(buffer, buffer + len); 
// here i want to pass buf as uint8_t* to onther func 
pack((uint8_t*)buf, len));// error 
} 

IntelliSense: no suitable conversion function from "std::vector<uint8_t, std::allocator<uint8_t>>" to "uint8_t *"

传递第一个元素的地址。

pack(&buf[0], len);
