Parameters

[in]	portName	The name of the asyn port to connect to
[in]	addr	The address on the asyn port to connect to
[in]	drvInfo	The drvInfo string to identify which property of the port is being connected to
[in]	timeout	The default timeout for all communications between the client and the port driver

asynInt32Client() [2/2]

asynInt32Client::asynInt32Client ( const char *  portName, const char *  drvInfo, int  addr = 0, double  timeout = DEFAULT_TIMEOUT  )

inline

~asynInt32Client()

virtual asynInt32Client::~asynInt32Client ( )

inlinevirtual

Member Function Documentation

getBounds()

virtual asynStatus asynInt32Client::getBounds ( epicsInt32 *  low, epicsInt32 *  high  )

inlinevirtual

Returns the lower and upper limits of the range of values from the port driver.

Parameters

[out]	low	The low limit
[out]	high	The high limit

read()

virtual asynStatus asynInt32Client::read ( epicsInt32 *  value )

inlinevirtual

Reads an epicsInt32 value from the port driver.

Parameters

[out]

value

The value read from the port driver

registerInterruptUser()

virtual asynStatus asynInt32Client::registerInterruptUser ( interruptCallbackInt32  pCallback, void *  userPvt = 0  )

inlinevirtual

Registers an interruptCallbackInt32 function that the driver will call when there is a new value.

Parameters

[in]	pCallback	The address of the callback function
[in]	userPvt	The user-defined pointer to be passed to the callback function

write()

virtual asynStatus asynInt32Client::write ( epicsInt32  value )

inlinevirtual

Parameters

[in]

value

The value to write to the port driver
