VioWrtCharStrAtt (FAPI)

This call writes a character string with repeated attribute to the display.

Syntax

VioWrtCharStrAtt (CharStr, Length, Row, Column, Attr, 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.

Attr (PBYTE) - input

Address of the attribute(s) (1 or 3 bytes) to be used in the display buffer for each character of the string written.

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 with a repeated 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.
