Question

I’m using sockets with C++. The program simply requests an HTTP page, reads it into a buffer buf[512], and then displays the buffer. However pages can contain more data than the buffer, so it will cut off if there is no more space left. I can make the buffer size bigger, but that doesn’t seem like a good solution. This is the code that I am using:

char buf[512];
int byte_count = recv(sockfd, buf, sizeof(buf), 0);

What would be an alternative to a char array in C++ to use as a buffer?

Depends on what you intend to do with the data. If you just want to dump it to an output stream, then the proper thing to do is to do what you’re doing, but do it in a loop until there’s no more data to read, writing the buffer to the output stream after each read.
