Writes an attribute to the display a specified number of times.

Syntax

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

Parameters

Attr (PBYTE) - input: Attribute to be written.; Address of the attributes (1 or 3 bytes) to be written.
Times (ULONG) - input: Repeat count.; The number of times to write the attribute.
Row (ULONG) - input: Starting row position.
Column (ULONG) - input: Starting column position.
VioHandle (HVIO) - input: VIO presentation-space handle.; This must be 0, unless the caller is a Presentation Manager application; in this case, it must be the value returned by VioCreatePS.

Return Code

rc (APIRET) - returns

VioWrtNAttr returns one of the following values:

0 NO_ERROR
355 ERROR_VIO_MODE
358 ERROR_VIO_ROW
359 ERROR_VIO_COL
421 ERROR_VIO_INVALID_PARMS
436 ERROR_VIO_INVALID_HANDLE

Remarks

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