Detailed Description

Time and duration types and defines.


Define 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.
