NB: If there is a | in front of the word, that means the author did not
intend this function to be available to the end user.

You have three choices:

1) Remove the | and recompile the kernel (not recommended as next time you
get a maintenance release, that change will be overwritten).

2) Copy the source code (without the '|') into your application.

3) Find a different way :-)
