I tell help
This is last suggestion that I tell, where is the problem now for segmentation
fault:

Enter .help for instructions
sqlite select load_extension('/root/soundex.so');
sqlite select soundex('saverio');
S010
How must I interpret this output:
bash-3.1# gcc -O0 -g -shared labsinf.c -o soundex.so

I don't understand where is
I modified row in function:
sqlite3_result_text(ctx,(const char*)ret, 4, SQLITE_TRANSIENT);
I know that dimension is 4, but my shell don't return values for extension
function also with half.c example copied from wiki:

Excuse me for my stupid topic, but I am crazying to find error in program below.
My output is:

The errror is for sqlit3_extension_init row, but I don't see strange things
#include stdio.h
But I don't understand where is the error in row below:

Can some suggest me something?

I have a new problem, I am attempting add extension function to sqlite3.
My program labsinf.c now build successfully, but I didn't add my extension. I
don't understand what it is miss.
Help me please.
The program labsinf.c make inf, and after I typed ./inf, it makes dbforext.db.
Some output is

How can I to pass parameters in sql string?
For example, I type:
sql = create table modulo(id, nome, classe, istanza);;
now, I'd like to insert a parametrized name for table. Like
echo 'create table $modulo(id, nome, classe, istanza)'
in shell scripting.
