Thanks!
I’m trying to transform the extension-functions.c in a persistent extension.
The original entry function is that:
int sqlite3_extension_init(
sqlite3 *db, char **pzErrMsg, const sqlite3_api_routines *pApi){
SQLITE_EXTENSION_INIT2(pApi);
RegisterExtensionFunctions(db);
return 0;
}
After reading this append you sent I’m trying something like this:
int sqlite3_extension_init(
sqlite3 *db, char **pzErrMsg, const sqlite3_api_routines *pApi){
int rc = SQLITE_OK;
SQLITE_EXTENSION_INIT2(pApi);
rc = RegisterExtensionFunctions(db, pzErrMsg, pApi);
if (rc == SQLITE_OK) {
rc = sqlite3_auto_extension(RegisterExtensionFunctions);
}
if (rc == SQLITE_OK) rc = SQLITE_OK_LOAD_PERMANENTLY;
return rc;
}
And I’ve changed the signature of the RegisterExtensionFunctions to receive the
pzErrMsg and pApi.
It’s not working yet, but I’m trying here. Am I on the right way?
