4.3.5. QryFetcTarg
•
Function name long QryFetcTarg
•
Usage
Searches for response values (Targets) in a specified range.
•
Argument
[IN] long lngPID
// Packet ID (specifies the value acquired
// by BisOpenPacket)
long lngTr
// Specifies the analysis channel
// (BIS_TRACx_xxx)
long lngStrPnt
// The point where the search starts
long lngStpPnt
// The point where the search ends
double dblTgt
// A response value to be searched for
[OUT] double * dblFreq // Returns the frequency of the searched point.
long * lngPleft
// Returns the (left side) point value of
// the searched point.
long * lngPright // Returns the (right side) point value
// of the searched point.
•
Return value 0: Normal
1: The IngStrPnt or IngStpPnt argument is incorrectly specified.
8: Search Error (No Target was found).
Other: Refer to Section
•
Description The point where the response value specified using dblTgt is crossed is searched
for in the range specified using the arguments lngStrPnt and lngStp- Pnt. Then,
the frequency, and the left-side point value and the right-side point value of the
crossed point are stored in the arguments of dblFreq, lngPleft and lngPright,
respectively.
If lngStrPnt > lngStpPnt, the search direction is reversed.

•
Function name long QryFetcVal
•
Usage
Determines the response value (measurement value) for a specified point posi-
tion
•
Argument
[IN] long lngPID
// Packet ID (specifies the value acquired
// by BisOpenPacket)
long lngTr
// Specifies the analysis channel
// (BIS_TRACx_xxx)
long lngPntN
// A point position to determine a
// measurement value
[OUT] double * dblValue // Return the measurement value.
•
Return value
0: Normal
1: The IngPntN argument is incorrectly specified.
Other: Refer to Section
•
Description
The response value (measurement value) for the position specified with the
argument lngPntN is determined.
Then, the value is saved in the variable specified with the argument dblValue.
