Имя (Name)
uuid_time - extract the time at which the UUID was created
Синопсис (Synopsis)
#include <uuid.h>
time_t uuid_time(uuid_t
uu, struct timeval *
ret_tv)
Описание (Description)
The uuid_time
() function extracts the time at which the supplied
time-based UUID uu was created. Note that the UUID creation time
is only encoded within certain types of UUIDs. This function can
only reasonably expect to extract the creation time for UUIDs
created with the uuid_generate_time(3) and
uuid_generate_time_safe(3) functions. It may or may not work with
UUIDs created by other mechanisms.
Возвращаемое значение (Return value)
The time at which the UUID was created, in seconds since January
1, 1970 GMT (the epoch), is returned (see time(2)). The time at
which the UUID was created, in seconds and microseconds since the
epoch, is also stored in the location pointed to by ret_tv (see
gettimeofday(2)).
