Returns the coordinates of the cursor.
Syntax
#define INCL_VIO #include <os2.h> PULONG Row; /* Row return data. */ PUSHORT Column; /* Column return data. */ HVIO VioHandle; /* Presentation-space handle. */ APIRET rc; /* Return code. */ rc = VioGetCurPos(Row, Column, VioHandle);
Parameters
- Row (PULONG) - output
- Row return data.
- Address of the current row position of the cursor, where 0 is the top row.
- Column (PUSHORT) - output
- Column return data.
- The address of the current column position of the cursor, where 0 is the leftmost column.
- VioHandle (HVIO) - input
- Presentation-space handle.
- This must be zero, unless the caller is a Presentation Manager application; in this case, it must be the value returned by VioCreatePS
Return Code
rc (APIRET) - returns
VioGetCurPos returns one of the following values:
- 0 NO_ERROR
- 355 ERROR_VIO_MODE
- 421 ERROR_VIO_INVALID_PARMS
- 436 ERROR_VIO_INVALID_HANDLE
