My question is,

1: can two modules export symbols to "each other". (exporting symbol and including .h file is sufficient??)

2: I am compiling a kernel module  and exporting few symbols, which another kernel      module (compiled with option obj-y ) will use. Is it possible first of all?

 what is the way to achieve this (exporting symbol and including .h file is sufficient??)

thanks in advance,
