Pragma once vs include guards?
Pragma synchronous = OFF.
For older versions of SQLite-
Consider a less paranoid journal mode(Pragma journal_mode).
Pragma is a rare type of love that stands
the test of time and can weather any storm.
(Of course I could use a Pragma to turn off the warning as well but I prefer this way.).
These are' ident'(always),' Pragma'(only if the preprocessor does not handle the Pragma itself),
and' define' and' undef'(with certain debugging options).
Pragma once' does not have the problems that‘ import' does,
but it is not recognized by all preprocessors, so you cannot rely on it in a portable program.
There is also a directive, Pragma GCC system_header,
which tells GCC to consider the rest of the current include file a system header, no matter where it was found.
