VioWrtCellStr (FAPI)

This call writes a string of character-attribute pairs (cells) to the display.

Syntax

VioWrtCellStr (CellStr, Length, Row, Column, VioHandle)

Parameters

CellStr (PCH) - input

Address of the string of character-attribute(s) cells to be written.

Length (USHORT) - input

Length, in bytes, of the string to be written. Each character-attribute(s) cell is 2 or 4 bytes.

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 string write gets to the end of the line and is not complete, the string 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 a character-attribute string to the Advanced VIO presentation space. The caller must specify the starting location on the presentation space where the string is to be written.

HVIO    VioHandle;     /* Video handle */

USHORT  rc;            /* return code */
