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.

Example Code

C Binding

#define INCL_VIO

USHORT  rc = VioWrtCellStr(CellStr, Length, Row, Column, VioHandle);

PCH              CellStr;       /* String to be written */
USHORT           Length;        /* Length of string */
USHORT           Row;           /* Starting row position for output */
USHORT           Column;        /* Starting column position for output */
HVIO             VioHandle;     /* Video handle */

USHORT           rc;            /* return code */

MASM Binding

EXTRN  VioWrtCellStr:FAR
INCL_VIO            EQU 1

PUSH@  OTHER   CellStr       ;String to be written
PUSH   WORD    Length        ;Length of string
PUSH   WORD    Row           ;Starting row position for output
PUSH   WORD    Column        ;Starting column position for output
PUSH   WORD    VioHandle     ;Video handle
CALL   VioWrtCellStr

Returns WORD
