Alright two questions:
1) Right now i run my client application, i enter the hostname and i use the getbyhostname() function to get its IP. then connect that host on whatever port. I want to prompt the user for the ip to connect to instead of hostname. so the user enters a string xxx.xxx.xxx.xxx and i want i need to set the struct sockaddr_in 's IP address to the IP address entered then connect to it. so how do i do that? how do i connect to a server just by knowing the IP address of that server and the port i want to connect to.
2) i use the sendto() function to send a certain char* from client to server. my server recieves it using:
recvfrom returns the size of the buffer recieved. so if i send the string "hello" i recieve "hello" on the server with a length of 5. now how can i send the string "hello server" with a space between them? i did some investigation on this. at first i thought that i actually recive "hello server" but the size returned by the recvfrom() function would be 5 instead of 12. but i tried printing buffer[7] which should be "s" and that did not work. so i came to the conclusion that the send function apparently cuts the string off at the space, maybe it considers it a null..

thanks for the help guys. sorry i blabbed alot, just trying to clarify.

ok i found an answer to my first question... use this line of code:
where IP is a char* xxx.xxx.xxx.xxx
and sendhost is of type sockaddr_in

strlen returns the number of bytes (char's) already in the arrary. Perhaps you want sizeof(temp); instead.
