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.

DWORD ACE_LOW_DWORD ( ACE_QWORD  q  )  [inline]
ACE_QWORD ACE_MAKE_QWORD ( DWORD  lo,

) [inline]
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.
