Quick Question about Reading from HTML Page

Ok So our Professor gave us an assignment for a program, I"VE never worked with C before. i've done c++,java,html and some PERL

anyways
basically we repeat a webpage like this:
http://cor.cs.uky.edu:8800/CS316post.html

(I have the actual webpage done no prob) it's working like it should. (it's basically a copy)
anyways this is just a beginning web programming class so it's nothing fancy.

ANYWAYS
we basically are given some of like a C server....code, it's supposed to be kinda like an apache code (btw im assuming this is C#, he said it's C, arent C# and C the same thing? if not i apologize)

but lets say I put some stuff in the text field and select radio buttons, basically my webpage I send back once I hit submit should say this:

file+directory=%7Epaulp%2FHTML&option=number&data=HELLOTHAR&hiddenValue=0

im basically reprinting the tokens back? pretty easy right? well i dont know C at ALL
but I did get this much:
but see it needs to be able to do this both in POST and GET formats, I figure POST is the easiest.....since it just shows what is selected, altho im unsure if what i have is a POST or a GET method......
im so confused.

Code:

int main(int argc, char *argv[]) { FILE *file_ptr; char portnum[10]; char readData[10]; const char PARMFILE[] = "parm.txt"; int scannum; int foundport = 0; // Signal SigCatcher to eliminate zombies signal(SIGCHLD,SigCatcher); file_ptr = fopen(PARMFILE, "r"); // open file for reading if (file_ptr != NULL) { // use fscanf to read line and get tokens from line scannum = fscanf(file_ptr,"%s",readData); while(scannum > 0 && foundport == 0) { // First token is port number strcpy(portnum,readData); // ONLY reads one token :( i need to read all foundport = 1; // For program 1, need to keep reading multiple lines.... scannum = fscanf(file_ptr,"%s",readData); } } else { error("Cannot open parameter file\n"); }

thats the basic reading line code that i was able to get.
parm.txt is like a text file with port numbers and such (i dunno much about ports and such....im afraid)
the rest is stuff HE provided, but anyways basically I need to read all tokens and print them back. also when i try to compile and run this file i get a "error on binding" yet it compiles fine gcc -o (using unix compiler) so i dunno *** is with that. we use a multilab type of thing on putty to do all this and run the server.
cor.cs.uky.edu is the schools server I do know that much.

sorry if I sound confusing but basically I have to edit server.c (the code I just gave) to print out what his did (the tokens of what was put in the cs316.html radio and text buttons)
I got it to print out 1 (i think) but I need it to print out all of them.

also I have the error cases if file doesn't open but no need for those in here.

any idea's? thanks (TOTAL new to C so any idea's will help)

Here is the rest of his code.....dunno if it helps tho as it's mostly just opening ports and such (i think)

Code:

// When request received fork a new thread to handle it pid = fork(); if (pid < 0) error("ERROR on fork\n"); if (pid == 0) { // request received close(sockfd); // Create thread and socket to handle httpthread(newsockfd,cli_addr); exit(0); } else close(newsockfd); } /* end of while */ return 0; /* we never get here */ } // httpthread // There is a separate instance of this function // for each connection. It handles all communication // once a connnection has been established. // If the server is canceled while waiting for a client // request, a "zombie" may result. See the link in the prolog. // We will ignore this in this simple program. void httpthread (int sock, // socket to use struct sockaddr_in cli_addr) // client address { int n; char space[] = " "; char buffer[10000]; // buffer for all data from client bzero(buffer,10000); char buffer1[10000]; // buffer for each read of client data // buffer1 is concatentated to buffer // on each read bzero(buffer1,10000); int count = 1; fd_set read_flags,write_flags; FD_ZERO(&read_flags); // Zero the flags FD_ZERO(&write_flags); FD_SET(sock, &read_flags); struct timeval waitd; waitd.tv_sec = 1; // Make select wait up to 1 second for data waitd.tv_usec = 0; // and 0 milliseconds. // read data from client while (count > 0) { // select command sets count n = read(sock,buffer1,9999); if (n <= 0){ error("ERROR reading from socket in httpthread"); } else { strcat(buffer,buffer1); // concatenate it to previous data bzero(buffer1,1000); } // select checks if data is available from client // count is zero when all data is read count=select(sock+1, &read_flags,&write_flags, (fd_set*)0,&waitd); } // You can use fscanf or strtok to extract data from // client request: // request type(GET POST) // file name for GET request // This program doesn't care, just echoes back // what was sent to it handleRequest(sock, buffer); // On return, log request // File locking // For a "real" server, a lock must be obtained // on the log file before writing to it // This program (and program 1) will ignore this FILE *file_ptr; // Open log file for appending file_ptr = fopen("logfile.txt", "a"); time_t timer; timer=time(NULL); // get time or request // get client IP address and write to file fputs((char*)inet_ntoa(cli_addr.sin_addr), file_ptr); fputs(space, file_ptr); // get time of request and write to file fputs((char*)asctime(localtime(&timer)), file_ptr); fclose(file_ptr); } // handleRequest void handleRequest(int sock, // socket to use char* buffer) // buffer of client data { int buffersize; // buffer size as integer char buffsizechar[5]; // buffer size as chars to send // reponse line: write(sock,HTTP,strlen(HTTP)); write(sock,RC200,strlen(RC200)); write(sock,RC200MSG,strlen(RC200MSG)); // headers: write(sock,CONTENTTYPE,strlen(CONTENTTYPE)); write(sock,CONTENTLENGTH,strlen(CONTENTLENGTH)); buffersize = strlen(buffer); // size as int // zero the char size field bzero(buffsizechar,sizeof(buffsizechar)); sprintf(buffsizechar,"%i",buffersize); // convert to chars write(sock,buffsizechar,strlen(buffsizechar)); write(sock,BLANKLINE,strlen(BLANKLINE)); // end last header line // headers terminated by blank line write(sock,BLANKLINE,strlen(BLANKLINE)); // Data received from client echoed back to client write(sock,buffer,strlen(buffer)); return;
