PRB: Windows FatalExit 0x0280 Error Caused by FAR WinMain


The information in this article applies to:

  • Microsoft Windows Software Development Kit (SDK) versions 3.0, 3.1


When an application is launched, a FatalExit 0x0280 (ERR_GMEMHANDLE, invalid global handle) error occurs in Windows 3.0, or a general protection (GP) fault occurs in Windows 3.1.


The application declares the WinMain function as a FAR function. The design of the Microsoft Windows kernel assumes that an application's entry point is a near function rather than a far function.


Remove the FAR keyword from the declaration of the WinMain function.

Additional query words: 3.00 3.10 rip gpf gp-fault
