Thanks you very much for the prompt for the answer.
“By default header files are indexed ONLY if they are included by a
source file” is NOT totally true because otherwise step 3 would not happen.
As I am working on a static analysis rule to check if a function
definition has a function prototype even after I comment the header out to have
the
function prototype unavailable the indexer keeps telling me the
function prototype is still OK.
What really brought my attention was that after Rebuilding the index I could
go back to step 1 behavior.
Thanks again for the info and I will think on another algorithm to
check this.
Regards,
Felipe

Does “Update
index immediately after every file-save” mean every time I do a file-save
operation the indexer is kept updated?
I have the
following case where the index does NOT seem to be updated correctly.
Given the
following header file contents:
#ifndef SAMPLE_H_
#define SAMPLE_H_
int h_function();
#endif /* SAMPLE_H_ */
And the
following source file contents:
//#include
"Sample.h"
int main(void) {
return function() *
EXIT_SUCCESS;
}
int h_function() {
return 55;
}
1.-When just
open the project and I do a F3 over h_function it takes me no where which makes
sense because the header that contains the function prototype is commented out.
2.-If I
uncomment the header Sample.h and I save the F3 over h_function starts working
taking me to the h_function prototype so far so good.
3.-But if I
comment again the line where I have the #include “Sample.h”, F3 over h_function
still works taking me to the prototype so the index seems to have OLD data.
The index is still up to date. Try to comment out int h_function();
instead and see what happens . F3 doesn't need an explicit
include to find declaration of h_function. This behavior is particularly
important for Add Include.
4.-Nevertheless
if rebuild the index (index->Rebuild) I get back the behavior when I just
opened the project (step 1).
Could you
explain why this happens please? Am I missing something?
By default header files are indexed only if they are included by a
source file. You can change this behavior in
Window->Preferences->C/C++->Indexer->Index unused headers. If
a header file was indexed once, it will be reindexed on any subsequent change
regardless of whether it's still included by a source file or not.
Thanks in
advance,
