The application of a few scripts in the semantic patch language
can occasionally help to improve some software, can't it?
Now I'll try again to present more detailed source code analysis results
according to specific software metrics.

I assumed that each source file (*.c) provides only functions which
unique names.

╚════════════╧═══════╧════════╝


Does such a table indicate that there are some function implementations
left over which will provide only the return value "zero" (or "NULL")?

A few specific examples:
* client_timeout_resend_expire
* config_parse_memory_limit
* transfer_on_log
* udev_rules_unref
* writer_free


Is this information worth for further considerations?
