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.
