Returns a value that indicates how a QuickWin program will behave when the exit function is called.
#include <io.h>
int _wgetexit( void );
QuickWin programs can optionally keep their windows on the screen after termination. How a program will behave at exit time depends on its current exit behavior setting. The _wgetexit function lets you examine the current exit behavior setting. This routine is used only in QuickWin programs; it is not part of the Windows API. For full details about QuickWin, see Chapter 8 of Programming Techniques (in the Microsoft C/C++ version 7.0 documentation set).
If the companion function _wsetexit has been called previously, _wgetexit returns the value that it set. This can be one of the following values:
| Value | Meaning |
| _WINEXITPROMPT | Prompt the user at exit time to determine whether the windows stay on the screen |
| _WINEXITNOPERSIST | The windows do not stay on the screen and there is no prompt to the user |
| _WINEXITPERSIST | The windows stay on the screen at exit |
If _wsetexit has not been called previously, the _wgetexit function returns _WINEXITPERSIST, the default exit behavior. For a description of how to use this exit behavior, see _wsetexit.
If successful, _wgetexit returns the current exit behavior setting value: _WINEXITPROMPT, _WINEXITNOPERSIST, or _WINEXITPERSIST. A return value of –1 indicates an error.
