VioWrtNAttr (FAPI)

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.

USHORT           Times;         /* Repeat count */
USHORT           Row;           /* Starting row position for output */
USHORT           Column;        /* Starting column position for output */
