How are you sending the records? Describe how you're writing the data to the socket connection.

i am sending records in a structure.... there r fields defined in the structure... one structure is being sent but not the second and the rest...

You're doing a direct write/send of the memory block of the structure? That is bad form for network communications. This is not portable and only works when the client/sender and server/receiver are running on identical architectures.

For better portability between systems a simple thing to do is marshal all your structure elements into a text string. Delimiters between fields help with parsing, and some kind of start/end sentinel values will help the code know when it has received a complete string.
