I tried sending the content of a buffer with send function and receive with recv function but I found out that the entire buffer content was not transmitted/the entire buffer content was not received. What can be the reason and how do I rectify this?

The reason can be that you haven't checked out the documentation of these two functions and you probably don't check their return value: send()[^], recv()[^]. Always check the return value for errors, and never assume that they sent the whole buffer. If they sent/received only part of the data then increase the pointer into your buffer and issue another send() or recv() call to send/receive the remaining data.
