meiSqNodeAnalogInPtr

Declaration

	long meiSqNodeAnalogInPtr(MEISqNode sqNode, long channel, long mask, long *ptr);
	Required Header: stdmei.h Change History: Added in the 03.04.00.

Description

meiSqNodeAnalogInPtr gets a controller memory pointer and mask of an analog input (channel on the SynqNet node sqNode) and writes them to the locations pointed to by ptr and mask. The memory pointer and mask obtained by this function can be used when setting up the data recorder or user limits.

sqNode	a handle to a SynqNet node object.
channel	an index to a node's analog input channel.
*mask	a pointer to a bitwise mask that corresponds to the specified word.
**ptr	a pointer to a controller address that contains the analog input word.

Return Values
MPIMessageOK
MPIMessageaARG_INVALID

Sample Code

The sample code below shows how to set up the data recorder to record analog channel 2 on node 1.


long mask;
long * pointer;
meiSqNodeAnalogInPtr( sqNode1, 2, &mask, &pointer );

void * points[MEIXmpMaxRecSize];
points[0] = pointer;
long pointCount = 1;
mpiRecorderRecordConfig(
   recorder,
   MPIRecorderRecordTypePOINT,
   pointCount,
   points );
