Determine the transaction state of a database

int sqlite3_txn_state(sqlite3*,const char *zSchema);

The sqlite3_txn_state(D,S) interface returns the current transaction state of schema S in database connection D. If S is NULL, then the highest transaction state of any schema on database connection D is returned. Transaction states are (in order of lowest to highest):

0. SQLITE_TXN_NONE
1. SQLITE_TXN_READ
2. SQLITE_TXN_WRITE

If the S argument to sqlite3_txn_state(D,S) is not the name of a valid schema, then -1 is returned.
