how to do socket programming in C over Http code example

Example: how to make a get request over socket c

char sendline[MAXLINE + 1], recvline[MAXLINE + 1];
char* ptr;

size_t n;

/// Form request
snprintf(sendline, MAXSUB, 
     "GET %s HTTP/1.0\r\n"  // POST or GET, both tested and works. Both HTTP 1.0 HTTP 1.1 works, but sometimes 
     "Host: %s\r\n"     // but sometimes HTTP 1.0 works better in localhost type
     "Content-type: application/x-www-form-urlencoded\r\n"
     "Content-length: %d\r\n\r\n"
     "%s\r\n", page, host, (unsigned int)strlen(poststr), poststr);

/// Write the request
if (write(sockfd, sendline, strlen(sendline))>= 0) 
{
    /// Read the response
    while ((n = read(sockfd, recvline, MAXLINE)) > 0) 
    {
        recvline[n] = '\0';

        if(fputs(recvline, stdout) == EOF)
        {
            printf("fputs() error\n");
        }

        /// Remove the trailing chars
        ptr = strstr(recvline, "\r\n\r\n");

        // check len for OutResponse here ?
        snprintf(OutResponse, MAXRESPONSE,"%s", ptr);
    }          
}
