--- 3.4 Objects which export symbols - export-objs --- 3.4 Objects which export symbols
When using loadable modules, not every global symbol in the No special notation is required in the makefiles for
kernel / other modules is automatically available, only those modules exporting symbols.
explicitly exported are available for your module. See also Documentation/modules.txt.
To make a symbol available for use in modules, to "export" it,
use the EXPORT_SYMBOL(<symbol>) directive in your source. In
addition, you need to list all object files which export symbols
(i.e. their source contains an EXPORT_SYMBOL() directive) in the
Makefile variable $(export-objs).
Example:
#drivers/isdn/i4l/Makefile
# Objects that export symbols.
export-objs := isdn_common.o
since isdn_common.c contains
EXPORT_SYMBOL(register_isdn);
which makes the function register_isdn available to
low-level ISDN drivers.
There exist a EXPORT_SYMBOL_GPL() variant with similar functionality,
but more restrictive with what may use that symbol. The requirement
to list the .o file in export-objs is the same.
