Queue

Q_Create

Creates a new queue and returns a handle to it. 

1
func int Q_Create()
Return value

The function returns a handle to a queue.

Q_Enqueue

Appends an integer to the back of the queue 

1
func void Q_Enqueue(var int queue, var int value)
Parameters
  • var int queue
    Handle of a queue
  • var int value
    The value to be appended to the queue

Q_IsEmpty

Checks if the queue is empty. 

1
func int Q_IsEmpty(var int queue)
Parameters
  • var int queue
    Handle of a queue

Return value

The function returns TRUE if the queue is empty, FALSE is returned otherwise.

Q_Advance

Removes the oldest value from the queue and returns it. 

1
func int Q_Advance(var int queue)
Parameters
  • var int queue
    Handle of a queue

Return value

The function returns the oldest value in the queue.

Q_Peek

Returns the oldest value in the queue without removing it. 

1
func int Q_Peek(var int queue)
Parameters
  • var int queue
    Handle of a queue

Return value

The function returns the oldest value in the queue.

Q_For

Function with the funcID is called with every element of the list as parameter.
The list element is passed to the function as a zCList pointer. 

1
func void Q_For(var int queue, var int funcID)
Parameters
  • var int queue
    Handle of a queue
  • var int funcID
    ID of function that is executed for all values in the queue (signature: void (zCList*))

Q_ForF

Like Q_For, but with function as a parameter instead of a function ID. 

1
func void Q_ForF(var int queue, var func f)
Parameters
  • var int queue
    Handle of a queue
  • var func f
    This function is executed for all values in the queue (signature: void (zCList*))

CallbackQueue

CQ_Create

Creates a new callback queue and returns a handle to it. 

1
func int CQ_Create()
Return value

The function returns a handle to a callback queue.

CQ_EnqueueNoData

Appends a function to the callback queue. 

1
func void CQ_EnqueueNoData(var int queue, var func function)
Parameters
  • var int queue
    Handle of a callback queue
  • var func function
    A function with no return value, expecting no parameter

CQ_EnqueueData

Appends a function together with a value to the callback queue. 

1
func void CQ_EnqueueData(var int queue, var func function, var int data)
Parameters
  • var int queue
    Handle of a callback queue
  • var func function
    A function with no return value, expecting an integer as a parameter.
  • var int data
    When calling function, this value is passed as a parameter

CQ_Enqueue

Appends a function together with an optional value to the callback queue. This function should not usually be used. Use CQ_EnqueueData and CQ_EnqueueNoData instead. 

1
func void CQ_Enqueue(var int queue, var int funcID, var int data, var int hasData)
Parameters
  • var int queue
    Handle of a callback queue
  • var int funcID
    The function ID of a function to be appended to the callback queue.
  • var int data
    If hasData is not 0, this value is passed to the associated function.
  • var int hasData
    Must be 0 if the function does not expect an integer as a parameter, otherwise not 0.

CQ_IsEmpty

Checks if no function is in the callback queue. 

1
func int CQ_IsEmpty(var int queue)
Parameters
  • var int queue
    Handle of a callback queue

Return value

The function returns TRUE if the callback queue is empty, FALSE is returned otherwise.

CQ_Advance

Executes the foremost function of the callback queue and removes it from the callback queue. 

1
func void CQ_Advance(var int queue)
Parameters
  • var int queue
    Handle of a callback queue

CQ_Exhaust

Executes all functions contained in the callback queue. 

1
func void CQ_Exhaust(var int queue)
Parameters
  • var int queue
    Handle of a callback queue
