The Use Of assert() In SQLite
(assert.html)
1. Assert() And Similar Macros In SQLite
The assert(X) macro is
part of standard C, in the
<assert.h> header file.
SQLite adds three other assert()-like macros named NEVER(X), ALWAYS(X),
and testcase(X).

C API: Report the internal text encoding state of an sqlite3_value object
(c3ref/value_encoding.html)
sqlite3_value_encoding()
The sqlite3_value_encoding(X) interface returns one of SQLITE_UTF8,
SQLITE_UTF16BE, or SQLITE_UTF16LE according to the current text encoding
of the value X, assuming that X has type TEXT. If sqlite3_value_type(X)
returns something other than SQLITE_TEXT, then the return value from ...
