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

VioWrtCharStr

This call writes a character string to the display.

Syntax

VioWrtCharStr (CharStr, Length, Row, Column, VioHandle)

Parameters

CharStr (PCH) - input : Address of the character string to be written.

Length (USHORT) - input : Length, in bytes, of the character string.

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 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.

Bindings

C Binding

#define INCL_VIO USHORT rc = VioWrtCharStr(CharStr, Length, Row, Column, VioHandle); PCH CharStr; /* String to be written */ USHORT Length; /* Length of character 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 VioWrtCharStr:FAR INCL_VIO EQU 1 PUSH@ OTHER CharStr ;String to be written PUSH WORD Length ;Length of character string PUSH WORD Row ;Starting row position for output PUSH WORD Column ;Starting column position for output PUSH WORD VioHandle ;Video handle CALL VioWrtCharStr Returns WORD
