aErr aStemCore_CmdFilter(

const unsigned char module, const unsigned char dataLength, const char* data, void* ref);

Parameters:

module	-	The IIC address of the module that will be sending a data packet.  This need not be the router.
dataLength	-	Number of packet data bytes.
data	-	Pointer to packet data bytes.
ref	-	Generic pointer that holds the match parameter.

Return Value:

This routine returns aTrue when the filter detects a match.

Description:

This routine returns aTrue when an incoming packet has a command ID that matches the parameter passed via the ref pointer.  This is a general-purpose filter routine that can handle most cases where a host application must await a reply from a module.

Many of the library routines that perform input operations use this filter.  This source file will need to be included in most applications that require input from a BrainStem module.
