Excessive RAM utilization

[GravisZro]

libt9 seems to solely depend on loading the entire database into RAM which seems to be about 2MB. This is excessive for anything utilizing an MCU.

My recommendation is to create file containing a data structure to utilize instead because flash memory access is sufficiently fast for this kind of task.

POSIX has database operations built into libc as listed here: https://pubs.opengroup.org/onlinepubs/9799919799/basedefs/ndbm.h.html

However, non-POSIX platforms can also use the sdbm which is a public domain implementation of the ndbm functions. https://github.com/davidar/sdbm/blob/master/sdbm.h

Alternatively, you can go with entirely custom code or in the exact opposite direction by using sqlite3.

Fascinating! Never heard about ndbm, might just use it for the challenge. There's a lot of good ways to implement this.

Oh, here's the POSIX spec website if you want to check if a function can be expected to work "everywhere": https://pubs.opengroup.org/onlinepubs/9799919799/

MSVCRT (Microsoft Visual C++ Runtime) implements most libc functions but lacks POSIX specific ones which includes dbm functions.

Already not planning on supporting MSVC since I have no way of testing and the library is primarily built to be run on Linux based phones.
