如何将char数组部分添加到vector <char>

Question

What is the best way to do this:

vector<char> content;
char MESSAGE[1024];
SUCCESSFUL = recv(sock_CONNECTION, MESSAGE, 1024, NULL);
for (int i = 0; i < SUCCESSFUL; i++)
    content.push_back(MESSAGE[i]);

I just found something like:

content.get_allocator = MESSAGE;

It doesn't have any errors, but I don't know how to cut MESSAGE from 0 to SUCCESSFUL .

Answer 1

content.insert(content.end(), MESSAGE, MESSAGE+SUCCESSFUL);

当然，在执行此操作之前，不要忘记检查recv()失败，并返回-1 。
