Hello ,
I want to know where EXPORT_SYMBOL macro is defined (in 2.4.18-3 kernel).
I saw in module.h that there are some #ifndef EXPORT_SYMBOL
that print an error if this symbols is nor defined , but searching
in the kernel sources did not gave me more results.
I also saw in the kernel Makefile that EXPORT_SYMBOL
appears in tags, but I do'nt know how to find the definition
for this macro.
Does somebody know ?
regards,
sting

It's optionally defined in module source code.
This symbol is used to tailor the symbol scoping rules implemented by
the module utilities. A module is free to define this symbol before
importing the standard module #include<> files. Use is voluntary
(2.4.x) but strongly recommended.
