Hi, Being relatively new to socket programming, I need some assistance in sending and receiving data over a TCP connected socket. I'm familiar with using send and recv commands to send and recv buffered character data, but what about if I want to send and recv data formatted within a structure? For example, main () { struct { int data1; double data2; bool indicator; }msg; // initialize data msg.data1 = 0; msg.data2 = 5.8; msg.inidicator = false; // send data ..... // receive data ..... } Are the send and recv commands the right ones to use for this type of information to send and receive data over a TCP connected socket or are there other commands that are better suited for this. When I use the send(socketfd, (char *)&msg, 0), it "appears" to work, but when receiving the data using recv(socketfd, (char *)&msg, 0), it returns with a -1. Thanks in advance for any help. -Martin NB: The commands must work on both the Windows and UNIX side, so Windows specific commands wouldn't work.

Hi, I have implemented a game that adds nodes to a list; in essense it is creating a tree. When I add a node to the tree, I use malloc to create memory for the node and push it onto a stack. I then pop it from the stack and do a check. If the check passes I push it back onto the stack, if it fails, I want to delete the node so I use free() to free the memory that was created for it. What is happening when you look at the Task Manger in Windows (XP), it shows the memory being allocated and freed for the application, but when you look at the field called "Commit Charge" within Task Manager, it shows a constant rise in the amount of virtual memeory being used. This continues to grow until the program ends with a memory allocation error. My question relates to resources/links/recommendations on how to better handle memory within a C++ program. I am using Microsoft VC++, version 6.0. I've looked through the code for memory leaks, but it it appears to do as it should; allocating and releasing memory in the proper order. Since it appears that memory leaks is the cause, I am looking for links or recommendations on how to find these leaks. Any recommendations or resources would be greatly appreciated. Thanks in advance. Martin
