double paramVal::getDouble

(

)

Gets the value for an double in the parameter library.

Exceptions:

ParamValWrongType	if type is not asynParamFloat64
paramValNotDefined	if the value is not defined

int paramVal::getInteger

(

)

Gets the value for an integer in the parameter library.

Exceptions:

ParamValWrongType	if type is not asynParamInt32
paramValNotDefined	if the value is not defined

char * paramVal::getName

(

)

asynStatus paramVal::getStatus

(

)

char * paramVal::getString

(

)

Gets the value for a string in the parameter library.

Exceptions:

ParamValWrongType	if type is not asynParamOctet
paramValNotDefined	if the value is not defined

const char * paramVal::getTypeName

(

)

epicsUInt32 paramVal::getUInt32

(

valueMask

)

Gets the value for a UInt32 in the parameter library.

Parameters:

[in]

valueMask

Mask to use when getting the value.

Returns:

Returns asynParamBadIndex if the index is not valid or asynParamWrongType if the parameter type is not asynParamUInt32Digital.

defined

)

void paramVal::setDouble

(

epicsFloat64

value

)

Sets the value for a double in the parameter library.

Parameters:

[in]

value

Value to set.

Returns:

Returns asynParamBadIndex if the index is not valid or asynParamWrongType if the parameter type is not asynParamFloat64.

void paramVal::setInteger

(

epicsInt32

value

)

Sets the value for an integer.

Parameters:

value

)

Sets the value for a string in the parameter library.

Parameters:

[out]

value

Address of value to set.

Returns:

Returns asynParamBadIndex if the index is not valid or asynParamWrongType if the parameter type is not asynParamOctet.

void paramVal::setUInt32	(	epicsUInt32	value,
		epicsUInt32	valueMask,
		epicsUInt32	interruptMask
	)

Sets the value for a UInt32 in the parameter library.

Parameters:

[in]	value	Value to set.
[in]	valueMask	Mask to use when setting the value.
[in]	interruptMask	Mask of bits that have changed even if the value has not changed

Returns:

Returns asynParamBadIndex if the index is not valid or asynParamWrongType if the parameter type is not asynParamUInt32Digital.
