TDftBitsBlk

You pass a record defined by the data type TDftBitsBlk to the PrGeneral procedure when you use the draftBitsOp or noDraftBitsOp opcode. For information on how to use the TDftBitsBlk record with the PrGeneral procedure, see "Enhancing Draft-Quality Printing" on page 9-31.

TYPE TDftBitsBlk =         {draft bits record}
   RECORD
      iOpCode:    Integer; {draftBitsOp or noDraftBitsOp opcode}
      iError:     Integer; {result code returned by PrGeneral}
      lReserved:  LongInt; {reserved}
      hPrint:     THPrint; {handle to the current TPrint record}
   END;

Field Description

iOpCode

Either the draftBitsOp or noDraftBitsOp opcode.

iError

The result code returned by the PrGeneral procedure.

lReserved

Reserved.

hPrint

A handle to a TPrint record, which is described on page 9-41. Your application should have already created this TPrint record and passed it to the PrintDefault or PrValidate routine to make sure that all of the information in the TPrint record is valid. The PrintDefault and PrValidate routines are described on page 9-56 and page 9-57, respectively.
