First, it is not a good idea to share variables between blocks because 
it may create side effects in particular if you want to share variables 
that can be modified by block execution (like input or output)

Nevertheless, if you really want to do that you could have  a look to 
the modules/scicos/src/c/import.c file (see the attached one if you dont 
have a source version)

The scicos_imp structure is available at simulation time and can be used 
to access to all C variables and data structures concerning the compiled 
model like global continuous state scicos_imp.x, all blocks inputs ans 
outputs,... as well as the array of blocks definition scicos_imp.blocks.
