Function Documentation

double ace_difftime (  time_t  t1, time_t  t0 )  [inline]

Helper for the ACE_OS::difftime() function. We moved the difftime code that used to be in ACE_OS::difftime() here because on some platforms "difftime" is a macro. Because of this, the name ACE_OS::difftime will cause errors. So in order to use the macro as it is defined but also keep the name ACE_OS::difftime, we use difftime first here in this inline function, and then undefine it. Definition at line 122 of file OS_NS_time.h. Referenced by ACE_OS::difftime(). { return difftime (t1, t0); }

DWORD ACE_HIGH_DWORD (  ACE_QWORD  q  )  [inline]

Definition at line 135 of file OS_NS_time.h. { return (DWORD) (q >> 32); }

DWORD ACE_LOW_DWORD (  ACE_QWORD  q  )  [inline]

Definition at line 134 of file OS_NS_time.h. { return (DWORD) q; }

ACE_QWORD ACE_MAKE_QWORD (  DWORD  lo, DWORD  hi )  [inline]

Definition at line 133 of file OS_NS_time.h. References ACE_QWORD. { return ACE_QWORD (lo) | (ACE_QWORD (hi) << 32); }

long ace_timezone (   )  [inline]

Helper for the ACE_OS::timezone() function. We put all the timezone stuff that used to be in ACE_OS::timezone() here because on some platforms "timezone" is a macro. Because of this, the name ACE_OS::timezone will cause errors. So in order to use the macro as it is defined but also keep the name ACE_OS::timezone, we use timezone first here in this inline function, and then undefine timezone. Definition at line 78 of file OS_NS_time.h. References ACE_NOTSUP_RETURN. Referenced by ACE_OS::timezone(). { #if defined (ACE_HAS_WINCE) TIME_ZONE_INFORMATION tz; GetTimeZoneInformation (&tz); return tz.Bias * 60; #elif defined (ACE_WIN32) && !defined (ACE_HAS_DINKUM_STL) return _timezone; // For Win32. #elif defined (ACE_WIN32) && defined (ACE_HAS_DINKUM_STL) time_t tod = time(0); // get current time time_t t1 = mktime(gmtime(&tod)); // convert without timezone time_t t2 = mktime(localtime(&tod)); // convert with timezone return difftime(t1, t2); // compute difference in seconds #elif defined (ACE_HAS_TIMEZONE) // The XPG/POSIX specification requires that tzset() be called to // set the global variable <timezone>. ::tzset(); return timezone; #elif defined (ACE_HAS_TIMEZONE_GETTIMEOFDAY) // The XPG/POSIX specification does not require gettimeofday to // set the timezone struct (it leaves the behavior of passing a // non-null struct undefined). long result = 0; struct timeval time; struct timezone zone; ACE_UNUSED_ARG (result); ACE_OSCALL (::gettimeofday (&time, &zone), int, -1, result); return zone.tz_minuteswest * 60; #else ACE_NOTSUP_RETURN (0); #endif }
