Syntax
#define INCL_VIO #include <os2.h> ULONG Height; /* The height of the character cell in pels. */ ULONG Width; /* The width of the character cell in pels. */ HVIO hvps; /* VIO presentation-space handle. */ APIRET rc; /* Return code. */ rc = VioSetDeviceCellSize(Height, Width, hvps);
Parameters
- Height (ULONG) - input
- The height of the character cell in pels.
- Width (ULONG) - input
- The width of the character cell in pels.
- hvps (HVIO) - input
- VIO presentation-space handle.
This is either 0 to indicate the default VIO session or a value returned by apiref refid='viocrps' form='textonly'..
Return Code
rc (APIRET) - returns
VioSetDeviceCellSize returns one of the following values:
- 0 NO_ERROR
- 421 ERROR_VIO_INVALID_PARMS
- 436 ERROR_VIO_INVALID_HANDLE
Remarks
If the device does not support the specified cell size, the cell size closest to the specified size is used. VioGetDeviceCellSize can be used to find the actual size selected. In OS/2 2.x, hvps cannot be 0.
