sending structure containing a pointer to another structure over TCP socket

[Abid Ghufran]

I am working on an application over fedora using c language and
sockets (TCP). I have to send a structure which contains a pointer to
another strcuture. Now what happens is that when the primary structure
(containing the pointer) gets sent, instead of the secondary structure
(pointed to) being sent, only its pointer get sent. This is quite
normal and obvious as the original strucutre, contains the pointer as
a data member, and does not contain as a member the structure being
pointed to.

I am using send and receive for this purpose. How can i manage the
send(ing) and receive(ing) of the primary and the secondary structure?

[The primary structure contains the control information and the
secondary structure contains the data information, and they together
form sort of a header and payload].

Thank you,
