Low-level socket-related functions.
Contains some base functions that both the client and server can use. As such, depending what we are being compiled for will determine what we can include. the client is designed have CFCLIENT defined as part of its compile flags.
Definition in file lowlevel.c.
int GetInt_String | ( | const unsigned char * | data | ) |
Basically does the reverse of SockList_AddInt, but on strings instead. Same for the GetShort, but for 16 bits.

void Send_With_Handling | ( | socket_struct * | ns, |
SockList * | sl | ||
) |
Calls Write_To_Socket to send data to the client.
The only difference in this function is that we take a SockList , and we prepend the length information.

int SockList_ReadPacket | ( | int | fd, |
SockList * | sl, | ||
int | len | ||

This reads from fd and puts the data in sl. We return true if we think we have a full packet, 0 if we have a partial packet, or -1 if an error occurred. The only processing we do is remove the initial size value. len (As passed) is the size of the buffer allocated in the socklist. We make the assumption the buffer is at least 2 bytes long.

This writes data to the socket. - It is very low level - all we try and do is write out the data to the socket provided (ns). buf is the data to write, len is the number of bytes to write. IT doesn't return anything - rather, it updates the ns structure if we get an error.
