VioWrtNCell

Description

Writes a cell (character-attribute pair) to the display a specified number of times.

Syntax

#define INCL_VIO
#include <os2.h>

PBYTE     Cell;       /*  Attribute to be written. */
ULONG     Times;      /*  Repeat count. */
ULONG     Row;        /*  Starting row position. */
ULONG     Column;     /*  Starting column position. */
HVIO      VioHandle;  /*  VIO presentation-space handle. */
APIRET    rc;         /*  Return code. */

rc = VioWrtNCell(Cell, Times, Row, Column, VioHandle);

Parameters

Cell (PBYTE) - input

Attribute to be written.

The address of the character-attribute cell (2 or 4 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

VioWrtNCell 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.
