Description

Writes a character string with repeated attributes to the display.

Syntax

#define INCL_VIO
#include <os2.h>

PCH       CharStr;    /*  String to be written. */
ULONG     Length;     /*  Length, in bytes, of the character string. */
ULONG     Row;        /*  Starting row position. */
ULONG     Column;     /*  Starting column position. */
PBYTE     Attr;       /*  Attribute to be replicated. */
HVIO      VioHandle;  /*  VIO presentation-space handle. */
APIRET    rc;         /*  Return code. */

rc = 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.
