Detailed Description
Time Types and Macros.
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.
