VioWrtNAttr

This call writes an attribute to the display a specified number of times.

Syntax

 VioWrtNAttr (Attr, Times, Row, Column, VioHandle)

Parameters

  • Attr (PBYTE) - input : Address of the attribute(s) (1 or 3 bytes) to be written.
  • Times (USHORT) - input : Number of times to write the attribute.
  • Row (USHORT) - input : Starting cursor row.
  • Column (USHORT) - input : Starting cursor column.
  • VioHandle (HVIO) - input : This must be zero unless the caller is a Presentation Manager application, in which case it must be the value returned by VioGetPs.

Return Code

rc (USHORT) - return

Return code descriptions are:

  • 0 NO_ERROR
  • 355 ERROR_VIO_MODE
  • 358 ERROR_VIO_ROW
  • 359 ERROR_VIO_COL
  • 436 ERROR_VIO_INVALID_HANDLE
  • 465 ERROR_VIO_DETACHED

Remarks

If a repeated write gets to the end of the line and is not complete, the write continues at the beginning of the next line. If the write gets to the end of the screen, the write terminates.

PM Considerations

Write an attribute code to the Advanced VIO presentation space a specified number of times. The caller must specify the starting location on the presentation space where the string is to be written.
