RE: help with unused functions

[William Gacquer]

Thanks for being so fast!

should in look in the ".to" or the ".by" databases? I see no other database
to look at to retrieve the "access" status of a function.

But when I have an isolated function - foo(), for instance - in the code
that neither used nor referring to anything, foo() is visible in .fil, .fu
but not .to and .by.

Does that mean that SN is not able to find the isolated functions?

Take a look at share/sdk/api/tcl/database/examples/unused.tcl
in the install dir. It prints unused variables, you will
have to adapt it a bit but it should be of some help.
There are other examples in that same dir that can
help you get started.

Correct.

   But when I have an isolated function - foo(), for instance - in the
   code that neither used nor referring to anything, foo() is visible in
   .fil, .fu but not .to and .by.

That's right.

No, it means it has no cross-references.

help with unused functions

[William Gacquer]

Can somebody send me a short tcl script or C code that retrieves all unused
functions in a C project?

I apologize for asking this kind of question but I am in hurry : 2 days to
finish our game....

Thanks in advance.
