time()
| |||
| Home > The C and C++ libraries > time() | |||
This is the standard C library time() function
from time.h.
The default implementation of this function uses semihosting.
Syntax
time_t time(time_t *timer);
The return value is an approximation of the current calendar time.
The value -1 is returned if the calendar
time is not available. If timerNULL pointer, the return value is also
stored in timer
