Problem in erlang interface

[maruthavanan s]

Hi,

I want to establish communication between C node and Erlang node, for that 
I’m using ei_connect_init() function and ei_connect. There is no [problem in 
establishing connection between two processes but when I tried to receive 
message from C node using the library function ei_receive_msg(), the 
function fails with value ERL_EXIT. In ei_receive_msg() I have used the 
following parameters

            ei_xreceive_msg(sockfd,&msg,&buff)

            sockfd=obtained on establishing connection with C node

            msg is  declared as erlang_msg msg;

and buff is obtained by

ei_x_buff buff;
ei_x_new(&buff);
