Namespaces
namespace	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

ace_asctime_r_helper()

char * ace_asctime_r_helper ( const struct tm * t, char * buf )

inline

ace_difftime()

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.

ace_gmtime_r_helper()

struct tm * ace_gmtime_r_helper ( const time_t * clock, struct tm * res )

inline

ace_localtime_r_helper()

struct tm * ace_localtime_r_helper ( const time_t * clock, struct tm * res )

inline

ace_timezone()

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.
