To write time in standard format to log files. To convert time (now () to character format "YYYY-MM-DD hh: mm: SS Zzz"
Write this function, Delphi system itself also with the Conversion Function formatdatetime ('yyyy-MM-DD hh: mm: SS zzz', now ())
You can also implement this function. Considering that this is a fixed-format conversion function for further optimization.
// Actual test results
Run 1,000,000 formatdatetime () ==> 2825 Ms
Sfformatdattime () ==> 545 Ms
// YYYY-MM-DD hh: mm: SS zzzP
layer, is the CPU L1 or L2 cache of the corresponding cache line invalid);
Third: Because the cached row of the cached variable stop in thread 1 's working memory is invalid, thread 1 reads the main memory again when the value of the variable stop is read.
Then thread 2 modifies the stop value (there are 2 operations here, of course). Modifying the value in the thread 2 working memory and then writing the modified value to memory invalidates the cached row of the cached variable stop in the w
before writing the volatile variable).Thread A writes a volatile variable, and then thread B reads the volatile variable, which essentially is thread a sending a message to thread B through main memory.
Does 5.volatile guarantee atomic sex?
Knowing from above that the volatile keyword guarantees the visibility of the operation, but does volatile guarantee that the operation of the variable is atomic?

In addition, ADODB should be familiar to people who have used ASP. Such friends should be very easy to accept.

Then thread 1 reads the latest correct value.
