Gets the position at which the presentation space maps to the window.
Syntax
#define INCL_VIO #include <os2.h> PULONG Row; PULONG Column; HVIO hvps; /* VIO presentation-space handle. */ APIRET rc; /* Return code. */ rc = VioGetOrigin(Row, Column, hvps);
Parameters
- Row (PULONG) - input
- Location to return the top-most row shown in the window.
- Column (PULONG) - input
- Location to return the left-most column shown in the window.
- hvps (HVIO) - input
- VIO presentation-space handle.
- This is either 0 to indicate the default VIO session, or a value returned by VioCreatePS.
Return Code
rc (APIRET) - returns
VioGetOrigin returns one of the following values:
- 0 NO_ERROR
- 421 ERROR_VIO_INVALID_PARMS
- 436 ERROR_VIO_INVALID_HANDLE
Remarks
In OS/2 2.x, hvps cannot be 0.
