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_greater_than ( const struct DDS_Time_t l,
const struct DDS_Time_t r 
)
Returns:
DDS_BOOLEAN_TRUE if the first time is greater than the second.
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_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_equal ( const struct DDS_Duration_t self,
const struct DDS_Duration_t other 
)
Parameters:
self<<in>> Duration to compare. Cannot be NULL.
other<<in>> Duration to be compared to this one. Cannot be NULL.
Returns:
DDS_BOOLEAN_TRUE if the two objects contain the same value, DDS_BOOLEAN_FALSE otherwise.
DDS_Boolean DDS_Duration_is_zero ( const struct DDS_Duration_t duration)
Returns:
DDS_BOOLEAN_TRUE if the given duration is of zero length.
