This is part of Family API which allow to create dual-os version of program runs under OS/2 and DOS

Note: This is legacy API call. It is recommended to use 32-bit equivalent

VioWrtNChar writes a character to the display a specified number of times.

Syntax

VioWrtNChar (Char, Times, Row, Column, VioHandle)

Parameters

;Char (PCH) - input : Address of the character to be written. ;Times (USHORT) - input : Number of times to write the character. ;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 a character to the Advanced VIO presentation space a number of times. 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 = VioWrtNChar(Char, Times, Row, Column, VioHandle); PCH Char; /* Character to be written */ USHORT Times; /* Repeat count */ 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 VioWrtNChar:FAR INCL_VIO EQU 1 PUSH@ OTHER Char ;Character to be written PUSH WORD Times ;Repeat count PUSH WORD Row ;Starting row position for output PUSH WORD Column ;Starting column position for output PUSH WORD VioHandle ;Video handle CALL VioWrtNChar Returns WORD
