av_gettime_relative()

int64_t av_gettime_relative ( void  )

Get the current time in microseconds since some unspecified starting point.

On platforms that support it, the time comes from a monotonic clock This property makes this time source ideal for measuring relative time. The returned values may not be monotonic on platforms where a monotonic clock is not available.

av_gettime_relative_is_monotonic()

int av_gettime_relative_is_monotonic ( void  )

Indicates with a boolean result if the av_gettime_relative() time source is monotonic.

Definition at line 71 of file time.c.

av_usleep()

int av_usleep ( unsigned  usec )

Sleep for a period of time.

Although the duration is expressed in microseconds, the actual delay may be rounded to the precision of the system timer.

Parameters
usec Number of microseconds to sleep.
Returns
zero on success or (negative) error code.
