A DDS_GuardCondition is a condition where the trigger_value is under application control.
| DDS_GuardCondition DDS_GuardCondition__alloc | ( | ) | [related] |
This routine allocates a DDS_GuardCondition.
The returned GuardCondition should be destroyed by a call to DDS_GuardCondition__free().
| void DDS_GuardCondition__free | ( | struct _GuardCondition * | gc | ) | [related] |
This routine destroys the provided DDS_GuardCondition.
The provided GuardCondition must have been previously allocated by a call to DDS_GuardCondition__alloc(). The caller must ensure that the GuardCondition is not attached to any WaitSets prior to calling DDS_GuardCondition__free().
| unsigned char DDS_GuardCondition_get_trigger_value | ( | DDS_GuardCondition | gc | ) | [related] |
This routine returns the current value of the trigger_value in gc.
A non-zero return value indicates that the trigger_value is TRUE.
A zero return value indicates that the trigger_value is FALSE.
| DDS_ReturnCode_t DDS_GuardCondition_set_trigger_value | ( | DDS_GuardCondition | gc, | |
| unsigned char | v | |||
| ) | [related] |
This routine set the current value of the trigger_value in gc.
A non-zero v argument indicates that the trigger_value is TRUE.
A zero v argument indicates that the trigger_value is FALSE. Setting the trigger value to a non-zero state will cause any threads that are waiting on a WaitSet with this GuardCondition attached to unblock. [In other words, the DDS_WaitSet_wait() routine will return if the WaitSet has this GuardCondition attached to it.]
