Function Documentation

RW_state RW__tmr_destroy (  RW_tmr *  tmr, RW_state  state )

Destroys the tmr RW handle. This should be called before exiting the routine doing the allocation, since it will cleanup any outstanding timers among other things. Parameters: tmr  The RW timer handle state  The current state Returns: The updated state. Warning: Failure to call this routine if a timer is still on the WUT que is fatal.

RW_state RW__tmr_lock (  RW_tmr *  tmr, RW_state  state )

Locks the resource. Parameters: tmr  The RW timer handle state  The current RW state Returns: The update RW state.

RW_state RW__tmr_unlock (  RW_tmr *  tmr, RW_state  state )

Unlocks the resource. Parameters: tmr  The RW timer handle state  The current RW state Returns: The update RW state.

RW_state RW__tmr_wait (  RW_tmr *  tmr, RW_state  state )

Waits until the timer expires or another task calls RW__tmr_wake indicating that another attempt be made to allocate the resource. Parameters: tmr  A previously initialized timer resource handle state  The current RW state Returns: The updated RW state.
