What is the fastest forward compatible way to gain use of the internal
buffer value recognizers such as "SQLITE_PRIVATE int sqlite3AtoF()" in
external C programs?
The goal is to efficiently compute exactly how SQLite would taxonomically
classify {numeric,float,integer,...} a buffer string value if it were used
in a statement.
Obviously the buffer under test could simply be composed into a "SELECT
typeof('$buffer')" statement and the result string read back from the db
exection step(). However prepare() + bind() + step() is slow compared to
directly calling natively compiled recognizer functions.
The computationally faster alternatives are (1) patch out SQLITE_PRIVATE on
the recognizer functions in a custom build to export them or (2)
copy/paste/fixup the recognizer function snippets into the external
compilation unit and hope they don't change too much.
What other alternatives are possible?
