Detailed Description

Time and duration types and defines.

Macro Definition Documentation

#define DDS_TIME_ZERO

The default instant in time: zero seconds and zero nanoseconds.

Function Documentation

DDS_Boolean DDS_Time_is_zero ( const struct DDS_Time_t time)

Check if time is zero.

Returns
DDS_BOOLEAN_TRUE if the given time is equal to DDS_TIME_ZERO or DDS_BOOLEAN_FALSE otherwise.
DDS_Boolean DDS_Time_is_invalid ( const struct DDS_Time_t time)
Returns
DDS_BOOLEAN_TRUE if the given time is not valid (i.e. is negative)
DDS_Boolean DDS_Duration_is_infinite ( const struct DDS_Duration_t duration)
Returns
DDS_BOOLEAN_TRUE if the given duration is of infinite length.
DDS_Boolean DDS_Duration_is_auto ( const struct DDS_Duration_t duration)
Returns
DDS_BOOLEAN_TRUE if the given duration has auto value.
DDS_Boolean DDS_Duration_is_zero ( const struct DDS_Duration_t duration)
Returns
DDS_BOOLEAN_TRUE if the given duration is of zero length.
