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


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


;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


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

<PRE> #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 */ </PRE>

MASM Binding


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 </PRE>
