Description

#define INCL_VIO #include <os2.h> HVIO VioHandle; /* Reserved. Must be 0. */ APIRET rc; /* Return code. */ rc = VioEndPopUp(VioHandle);
Parameters
- VioHandle (HVIO) - input
- Reserved. Must be 0.

rc (APIRET) - returns
VioEndPopUp returns one of the following values:
- 0 NO_ERROR
- 405 ERROR_VIO_NO_POPUP
- 421 ERROR_VIO_INVALID_PARMS
