Writes a character string to the display.

Syntax

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

Parameters

CharStr (PCH) - input
String to be written.
Address of the character string to be written.
Length (ULONG) - input
Length of character string.
Length, in bytes, of the character string.
Row (ULONG) - input
Starting row position.
Column (ULONG) - input
Starting column position.
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

VioWrtCharStr 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.
