Revision as of 19:24, 26 February 2017

Writes a character string with repeated attributes to the display.

Syntax

VioWrtCharStrAtt (CharStr, Length, Row, Column, Attr, VioHandle)

Parameters

CharStr (PCH) - input: String to be written.; Address of the character string to be written.
Length (ULONG) - input: Length, in bytes, of the character string.
Row (ULONG) - input: Starting row position.
Column (ULONG) - input: Starting column position.
Attr (PBYTE) - input: Attribute to be replicated.; Address of the attributes (1 or 3 bytes) to be used in the display buffer for each character of the string written.
VioHandle (HVIO) - input: VIO presentation-space handle.; This must be 0, unless the caller is a Presentation Manager application; in this case, it must be the value returned by VioCreatePS.

Return Code

rc (APIRET) - returns

VioWrtCharStrAtt returns one of the following values:

0 NO_ERROR
355 ERROR_VIO_MODE
358 ERROR_VIO_ROW
359 ERROR_VIO_COL
421 ERROR_VIO_INVALID_PARMS
436 ERROR_VIO_INVALID_HANDLE

Remarks

If a string write gets to the end of the line and is not complete, it continues at the beginning of the next line. If the write gets to the end of the screen, it terminates.
