gettimeofday()
Prototype
int gettimeofday(struct timeval *ptimeval,
struct timezone *ptimezone)
Commonly Called By
C/C++ programs
Device drivers
Thread-safe
See description.
Available from ISR
Yes.
Include
<sys/time.h>
Description
The gettimeofday() function obtains a time structure that indicates the current time. This time is
calculated using the elapsed number of system clock ticks, and the current time value set by the most
recent call to settimeofday().
If this function is called concurrently with a call to settimeofday(), the value returned by
gettimeofday() is unreliable; however, concurrent calls to gettimeofday() are legal.
