- iptr (ULONG) - Input
- The index of the desired system pointer.
- Possible values are in the following list:
- SPTR_ARROW
- Arrow pointer
- SPTR_TEXT
- Text I-beam pointer
- SPTR_WAIT
- Wait icon pointer
- SPTR_MOVE
- Move pointer
- SPTR_SIZENWSE
- Downward-sloping, double-headed arrow pointer
- SPTR_SIZENESW
- Upward-sloping, double-headed arrow pointer
- SPTR_SIZEWE
- Horizontal, double-headed arrow pointer
- SPTR_SIZENS
- Vertical, double-headed arrow pointer
- SPTR_APPICON
- Standard application icon pointer
- SPTR_ICONINFORMATION
- Information icon pointer
- SPTR_ICONQUESICON
- Question mark icon pointer
- SPTR_ICONERROR
- Exclamation mark icon pointer
- SPTR_ICONWARNING
- Warning icon pointer
- SPTR_ILLEGAL
- Illegal operation icon pointer
- SPTR_FILE
- Single file icon pointer
- SPTR_MULTFILE
- Multiple files icon pointer
- SPTR_FOLDER
- Folder icon pointer
- SPTR_PROGRAM
- Application program icon pointer
- pIconInfo (PICONINFO) - In/Out
- Icon data buffer.

Example Code
#define INCL_WINPOINTERS /* Or use INCL_WIN, INCL_PM, */ #include <os2.h> HWND hwndDesktop; /* Handle to the desktop window. */ ULONG iptr; /* The index of the desired system pointer. */ PICONINFO pIconInfo; /* Icon data buffer. */ BOOL rc; /* Return value. */ rc = WinQuerySysPointerData(hwndDesktop, iptr, pIconInfo);
