Datetimetostr function dedicated optimized edition (YYYY-MM-DD hh: mm: ss zzz)

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

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? Let's look at an example: public class Test {public volatile int

It provides Perl to access the database and uses consistent API call interfaces. I believe that friends who have used Perl + DBI will have a similar feeling when they use ADODB again. In addition, ADODB should be familiar to people who have used ASP. Such friends should be very easy to accept. Let's take a look at the simple usage of ADODB: // Introduc
