i want to write a constructor and destructor function in c for each of

I should register a routines which will be called before calling the

Does gcc provides anything like this.

gcc allows you to put a cleanup attribute on one of the
automatic variables which would give you the destructor.
http://gcc.gnu.org/onlinedocs/gcc-4.1.0/gcc/Variable-Attributes.html#Variable%20Attributes

To simulate a constructor, you can overload the function
by giving your constructor the same name as the
function and then use dlsym( RTLD_NEXT,...) to
call the function itself.

You're probably better off just modifying
the function to start by calling your constructor/initializer
and end by calling the destructor.
