#ifndef DB_H
#define DB_H
/* This is a library for importing title banks from SNOMAN files. Each bank is
* stored in a dictionary with the bank name and id as the key. For example, to
* load the DQXX files:
*
* dbval *dbval;
*
* db_init();
* load_file("DQXX_0000010000.dat");
* dbval = get_bank("DQCH",1);
* db_free();
*
* The return value of get_bank() is a pointer to the bank values. It's up to
* the caller to know the exact offsets for each value in the bank. Typically,
* SNO database title banks have a database header of 20 words and 10 unused
* words at the beginning of the bank.
*
* Note: Currently only 32 bit unsigned integers and 32 bit floating point
* numbers are supported. I don't think that any of the SNOMAN files have
* doubles. */
