Macro Definition Documentation

#define GlobusTimeAbstimeCopy(Dest, Src)Value: { (Dest).tv_sec = (Src).tv_sec; (Dest).tv_nsec = (Src).tv_nsec; }Copy the absolute time

#define GlobusTimeAbstimeDiff(Reltime, T1, T2)Value: { int __res = globus_abstime_cmp(&(T1), &(T2)); if(__res < 0) { (Reltime).tv_sec = (T2).tv_sec - (T1).tv_sec; (Reltime).tv_usec = (((T2).tv_nsec - (T1).tv_nsec) / 1000); if((Reltime).tv_usec < 0) { (Reltime).tv_sec--; (Reltime).tv_usec += 1000000; } } else if(__res > 0) { (Reltime).tv_sec = (T1).tv_sec - (T2).tv_sec; (Reltime).tv_usec = (((T1).tv_nsec - (T2).tv_nsec) / 1000); if((Reltime).tv_usec < 0) { (Reltime).tv_sec--; (Reltime).tv_usec += 1000000; } } else { (Reltime).tv_sec = 0; (Reltime).tv_usec = 0; } }Find the difference between the 2 absolute times.

#define GlobusTimeAbstimeGet(Abstime, Sec, USec)Value: { Sec = (Abstime).tv_sec; USec = ((Abstime).tv_nsec / 1000); }Seperates abstime structure into its components,sec and usec.

#define GlobusTimeAbstimeGetCurrent(Abstime)Value: { struct timeval __time; gettimeofday(&__time, GLOBUS_NULL); (Abstime).tv_sec = __time.tv_sec; (Abstime).tv_nsec = (__time.tv_usec * 1000); }Get the current time

#define GlobusTimeAbstimeInc(Abstime, Reltime)Value: { (Abstime).tv_nsec += ((Reltime).tv_usec * 1000); if((Abstime).tv_nsec >= 1000000000) { (Abstime).tv_sec++; (Abstime).tv_nsec -= 1000000000; } (Abstime).tv_sec += (Reltime).tv_sec; }Add reltime to abstime

#define GlobusTimeAbstimeSet(Abstime, Sec, USec)Value: { GlobusTimeAbstimeGetCurrent(Abstime); (Abstime).tv_nsec += (USec * 1000); if((Abstime).tv_nsec >= 1000000000) { (Abstime).tv_sec += ((Abstime).tv_nsec / 1000000000); (Abstime).tv_nsec = (Abstime).tv_nsec % 1000000000; } (Abstime).tv_sec += Sec; }Set the abstime structure to the sec and usec parameter values.

#define GlobusTimeReltimeCopy(Dest, Src)Value: { (Dest).tv_sec = (Src).tv_sec; (Dest).tv_usec = (Src).tv_usec; }Copy the relative time

#define GlobusTimeReltimeDivide(Reltime, Factor)Value: { (Reltime).tv_usec /= Factor; (Reltime).tv_sec /= Factor; }divide the reltime by factor

#define GlobusTimeReltimeMultiply(Reltime, Factor)Value: { (Reltime).tv_usec *= Factor; (Reltime).tv_sec *= Factor; if((Reltime).tv_usec >= 1000000) { (Reltime).tv_sec += ((Reltime).tv_usec / 1000000); (Reltime).tv_usec = (Reltime).tv_usec % 1000000; } }Multiple the reltime by factor

#define GlobusTimeReltimeSet(Reltime, Sec, USec)Value: { (Reltime).tv_usec = (USec); (Reltime).tv_sec = Sec; if((Reltime).tv_usec >= 1000000) { (Reltime).tv_sec += ((Reltime).tv_usec / 1000000); (Reltime).tv_usec = (Reltime).tv_usec % 1000000; } }Set the reltime structure to the sec and usec parameter values.

#define GlobusTimeReltimeToMilliSec(Milliseconds, Reltime)Value: { Milliseconds = ((Reltime).tv_sec * 1000) + ((Reltime).tv_usec)/ 1000; }Convert a relative time into a long in millisec units

#define GlobusTimeReltimeToUSec(SlpInt, Reltime)Value: { SlpInt = ((Reltime).tv_sec * 1000000) + ((Reltime).tv_usec); }Convert a relitive time into a long in usec units

Function Documentation

int globus_abstime_cmp (const globus_abstime_t * abstime_1, const globus_abstime_t * abstime_2)Compare two absolute times. This function returns an integer that reflects the comparison of two abstimes in the following way. 0 : values are the same. -1 : the first value is less than the second. 1 : the first value is greater than the second.

int globus_reltime_cmp (const globus_reltime_t * reltime_1, const globus_reltime_t * reltime_2)Compare two absolute times. This function returns an integer that reflects the comparison of two reltimes in the following way. 0 : values are the same. -1 : the first value is less than the second. 1 : the first value is greater than the second.

globus_bool_t globus_time_abstime_is_infinity (const globus_abstime_t * abstime)Returns a boolean that reflects whether or not abstime is infinity.

globus_bool_t globus_time_has_expired (const globus_abstime_t * abstime)Has abstime expired Returns a boolean that reflects whether or not abstime is less than the current time.

globus_bool_t globus_time_reltime_is_infinity (const globus_reltime_t * reltime)Returns a boolean that reflects whether or not reltime is infinity.
