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

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.
