  4. XINFO and C The XINFO C scanner delivers following information: • Which proprams are using which includes ? • Which programs are using which functions ? • Which programs are using a certain type ? • Which programs are calling external programs ? • Which programs are using which variables ? • Which programs are deleting rows from a DB2 table ? • ….

  5. C - Displays The displays for C

  6. C – General Info Selection panel “General Info” ..scroll up/down for more selection fields…

  7. C – General Info Resulting “General Info”

  8. C - Includes Search for Includes, e.g. all programs that include “errno.h”

  9. C - Includes These programs are using “assert.h” Direct read access to several sources

  10. C - System Search for all programs that are using system calls

  11. C - System These programs are using “getKundename”

  12. C - Functions Function “getKundename” causes problems. Where is it defined?

  13. C - Functions The function is defined in member “MINXI01”

  14. C – Function Call And now you want to know which programs are using this function: “Called Function” gives you the answer:

  15. C – Function Call Ok, no problem: The function is only used in two members

  16. C – Files And now you want to know which programs are using this function: “Called Function” gives you the answer:

  17. C - Files These programs are writing to the console

  18. C - Files Use the “group” function to get the members (and not all lines)

  19. C - Files All members where “stdout” is used, column Count shows you how often

  20. C – DB2 Access Which programs are updating table “VCONA”?

  21. C – DB2 Access Program DSN8CC1 is the only program that updates table “*Konto”

  22. C - Variables Which variables are declared, but not used?

  23. C - Variables The result shows all members (lines) where unused variables are declared

  24. C - Types Which programs are using streams?

  25. C - Types Here are all lines where bool are used…

  26. C - Types …use the group functions to get a list of all members…

  27. C - Types …here is a list of all members where streams are used
