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.
