Re: Detection of function calls in C and C++ codes

[Shigio YAMAGUCHI]

Hello,
> Where can i find the sqlite3 related database?

All tag files are SQLITE3 databases. Each database has a table named 'db'.
This is to realize SQLITE facility with less change.

$ sqlite3 GTAGS
sqlite> select count(*) from db;
11194
...
