Hi all, I'd like write extension for sqlite3 creating soundex function like
below:
void soundex() {
...
...
}
int main(int argc, char* argv[]) {
int rc;
sqlite3* db;
rc = sqlite3_open("dbforext.db",&db);
if (rc) {
fprintf(stderr, "E' impossibile aprire il file %s\n", sqlite3_errmsg(db));
sqlite3_close(db);
exit(1);
}
sqlite3_create_function(db, "soundex", 1, SQLITE_UTF8, NULL, soundex, NULL,
NULL);
sqlite3_close(db);
return 0;
}
but I have some questions:
1) The output of gcc is:
bash-3.1# gcc -lsqlite3 labsinf.c -o inf
labsinf.c: In function 'main':
labsinf.c:61: warning: passing argument 6 of 'sqlite3_create_function' from
incompatible pointer type
2) I must pass to soundex parameters for db connection, for my processing or
both?
3) I need a little example of function creating in sqlite3.
Thank you
savio
