Declaration:
typedef _export _stdcall int (*fInvertSecondaryTriggerSource)(int
InputMask);
TInvertSecondaryTriggerSource = function (InputMask: Integer): Integer;
stdcall;
Public Declare Function InvertSecondaryTriggerSource Lib
"VBDevKit52X.dll" (ByVal InputMask As Long) As Long
Parameters:
InputMask – Combination of constants TRIGGER_CHANNEL_A,
TRIGGER_CHANNEL_B, TRIGGER_EXTERNAL (bitmask). If the given bit is
set the appropriate trigger source will be considered valid.
