Detailed Description

Base class for asyn port drivers; handles most of the bookkeeping for writing an asyn port driver with standard asyn interfaces and a parameter library.

Constructor & Destructor Documentation

◆ asynPortDriver() [1/2]

asynPortDriver::asynPortDriver	(	const char *	portNameIn,
		int	maxAddrIn,
		int	interfaceMask,
		int	interruptMask,
		int	asynFlags,
		int	autoConnect,
		int	priority,
		int	stackSize
	)

Constructor for the asynPortDriver class.

Parameters

[in]	portNameIn	The name of the asyn port driver to be created.
[in]	maxAddrIn	The maximum number of asyn addr addresses this driver supports. Often it is 1 (which is the minimum), but some drivers, for example a 16-channel D/A or A/D would support values > 1. This controls the number of parameter tables that are created.
[in]	interfaceMask	Bit mask defining the asyn interfaces that this driver supports. The bit mask values are defined in asynPortDriver.h, e.g. asynInt32Mask.
[in]	interruptMask	Bit mask definining the asyn interfaces that can generate interrupts (callbacks). The bit mask values are defined in asynPortDriver.h, e.g. asynInt8ArrayMask.
[in]	asynFlags	Flags when creating the asyn port driver; includes ASYN_CANBLOCK and ASYN_MULTIDEVICE.
[in]	autoConnect	The autoConnect flag for the asyn port driver. 1 if the driver should autoconnect.
[in]	priority	The thread priority for the asyn port driver thread if ASYN_CANBLOCK is set in asynFlags. If it is 0 then the default value of epicsThreadPriorityMedium will be assigned by asynManager.
[in]	stackSize	The stack size for the asyn port driver thread if ASYN_CANBLOCK is set in asynFlags. If it is 0 then the default value of epicsThreadGetStackSize(epicsThreadStackMedium) will be assigned by asynManager.

◆ asynPortDriver() [2/2]

asynPortDriver::asynPortDriver	(	const char *	portNameIn,
		int	maxAddrIn,
		int	paramTableSize,
		int	interfaceMask,
		int	interruptMask,
		int	asynFlags,
		int	autoConnect,
		int	priority,
		int	stackSize
	)

Legacy constructor for the asynPortDriver class (DEPRECATED - please use the one above instead).

asynPortDriver >=R4-32 handles the table size automatically. Thus the paramTableSize parameter has been removed from the constructor. This constructor is provided for backwards compatibility. Users should switch to using the constructor ASAP.

◆ ~asynPortDriver()

asynPortDriver::~asynPortDriver ( )

virtual

Destructor for asynPortDriver class; frees resources allocated when port driver is created.
