Question

I have a simple echo server written in C, I would like to stop the server if it received the quit word

    int n;
    char buffer[256];
    while(strcmp(buffer,"quit") != 0)
    {
        n = read(sock,buffer,255);
        if (n < 0)
        {
        perror("ERROR reading from socket");
        exit(1);
        }

        printf("Here is the message: %s\n",buffer);
        printf("%d-%d\n", sizeof(buffer), strcmp(buffer,"quit"));

        n = write(sock,"I got your message",18);
        if (n < 0) 
        {
        perror("ERROR writing to socket");
        exit(1);
        }
  }

How can I compare the received buffer with a string?

Answer 1

I figured it out

void strip(char *s) {
    char *p2 = s;
    while(*s != '\0') {
        if(*s != '\t' && *s != '\n' && *s != '\r') {
                *p2++ = *s++;
        } else {
                ++s;
        }
    }
    *p2 = '\0';
}
