struct timeval tevent_timeval_add (const struct timeval *tv, uint32_tsecs, uint32_tusecs)
Add the given amount of time to a timeval structure.
Parameters:
tv The timeval structure to add the time.
secs The seconds to add to the timeval.
usecs The microseconds to add to the timeval.
Returns:
The timeval structure with the new time.
int tevent_timeval_compare (const struct timeval *tv1, const struct timeval *tv2)
Compare two timeval values.
Parameters:
tv1 The first timeval value to compare.
tv2 The second timeval value to compare.
Returns:
0 if they are equal. 1 if the first time is greater than the second. -1 if the first time is smaller than the second.
Compare two timeval values.
Return -1 if tv1 < tv2 Return 0 if tv1 == tv2 Return 1 if tv1 > tv2
