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.

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.
