 ACE_OS
 This namespace defines an OS independent programming API that shields developers from nonportable aspects of writing efficient system programs on Win32, POSIX and other versions of UNIX, and various real-time operating systems.

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_HIGH_DWORD ( ACE_QWORD  q)
inline
DWORD ACE_LOW_DWORD ( ACE_QWORD  q)
inline
ACE_QWORD ACE_MAKE_QWORD ( DWORD  lo,
DWORD  hi 
)
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.
