clearing a char* ??

I have a buffer called sendbuf. I am using it in a winsock program. It is set to the text the user entered, and then sent to the server. The problem is, that if a user types in "test" and then "a" the output would be "aest". I need to clear the sendbuf array so that it doesn't have leftover characters from the last input, but i cant figure out how!

sendbuf = ""; gets errors. :confused:

help would be nice :p


Thx in advance,

Code:

---

strcpy( sendbuf, "" );

---

or, if you know the size of sendbuf,

Code:

---

memset( sendbuf, '\0', size_of_sendbuf );

---

hummm... perhaps the buffer being cleared isn't the issue. I have tried using those to clear it, but the output still will be "aest" with input of "test" and "a"...

Code:

---

char *sendbuf = new char[32];
while(strcmpi(sendbuf, "quit")) {
    strcpy( sendbuf, "" );
    cout<<"input:";
    cin.getline(sendbuf, 32, '\n');
    send( m_socket, (char*)sendbuf, strlen(sendbuf), 0 );
}

---

Thats the code. If sendbuf != to "quit" it should input new data, and send it to the server.

:D :D :D

The problem was that I was forgetting to clear the buffer on the server too! :eek:

Thanks for the help!
