How to use SYMBOLs from another module

jinxcat · 09-14-2005, 03:17 PM

From what I understand, symbols point to either variables or functions, and it's really easy to export them (just with the EXPORT_SYMBOL(that_symbol); function, correct?)

If "module_a" has 2 symbols:

ma_fun to function "int ma_fun(int)"
ma_var to variable "int ma_var"

how could I use them to call them from inside module_b?

I think that's about right. Function names can be used as symbols AFAIK, so if you export them, you should be able to reference them from other modules. I'm not an expert on kernel programming though so I'd suggest checking the online version of Linux Device Drivers which should have something to say on the subject.
