    noob question

    Am I allowed to do:

    char *buffer = new char[128];
    sprintf(buffer, "some text here..");
    unsigned int textlen = strlen(buffer);
    recv(socket, buffer + textlen, 128 - textlen , 0);
    and I get in buffer "some text here..<received buffer here>" ?

    why do you post this in the C++ forum? It's C code.
    Operating Systems:
    - Ubuntu 9.04
    - XP

    Compiler: gcc

    Well if he posted on the C board, he'd probably be told to post on the C++ board...

    The new keyword has no place in C.

    It's a horrid mix of both - check the new call.

    Yes, so long as you solve all the other problems of
    - checking the return result
    - not allowing space to store a \0 to make it once again a C-string
    - not allowing for fragmented messages
    + some other stuff as well
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
