tbkGetProtocol
DLL Function int tbkGetProtocol(int *protocol)
C tbkGetProtocol(int *protocol);
QuickBASIC BtbkGetProtocol% (protocol%)
Visual Basic VBtbkGetProtocol% (protocol%)
Turbo Pascal tbkGetProtocol( protocol:DataP ):integer;
Parameters
protocol A pointer to a value that will be set to the current protocol chosen from the protocol codes listed below
(additional EPP implementation codes may be described in the README file).

tbkGetProtocol returns the current parallel port communications protocol. tbkInit initially
sets the protocol set to either TbkProtocol8 or TbkProtocol4, indicating either 8-bit or 4-bit
standard parallel port protocol. tbkSetProtocol may be used to specify other protocols.
tbkGetScan
DLL Function int tbkGetScan(uint *chans, uchar *gains, uchar *polarities, uint *count);
C tbkGetScan(unsigned *chans, unsigned char *gains, unsigned char *polarity,
unsigned *count);
QuickBASIC BtbkGetScan% (chans%, gains%, polarity%, ByVal count%)
Visual Basic VBtbkGetScan% (chans%(), gains%(), polarity%(), count%)
Turbo Pascal tbkGetScan( chans:WordP; gains:ByteP; polarity:ByteP; count:word ):integer;
Parameters
uint *chans An array to hold up to 512 channel numbers or 0 if the channel information is not desired. See table
at end of chapter for valid values.
uchar *gains An array to hold up to 512 gain values or 0 if the channel gain information is not desired. See table at
end of chapter for valid values.
uchar polarity Zero value causes TempBook to default to Unipolar mode. Non-zero value causes default Bipolar
mode. All ADC conversions except those started with
tbkSetScan will use the default polarity.
uint count A variable to hold the number of values returned in the chans and gains arrays.
Returns TerrNoError - No error

tbkGetScan reads the current scan sequence consisting of up to 512 channels, gains and
polarities.
