Re: [Discuss-gnuradio] Shared varible between blocks

[Michael Dickens]

IIRC: The "standard C" way to do this is:

In one, and only one, .cc file, do at the top level (not in any class,  
method, or function definition), e.g.:

int foo = 0;

then in the .h file do:

extern int foo;

and you should be able to access 'foo' from any code the includes  
that .h file.
