Typedef Documentation

typedef struct timespec kal_time_t

Implementation of kal_time_t through a timespec structure.

Note:

This implementation also works when compiled in user-space with rt-sim. Kernel-dependent long time information.

When representing negative values, microseconds and nanoseconds are always read as positive, while seconds are read as negative.
