PRB: User-Defined onexit/atexit/cexit Not Called If /MD or /MDd

• Microsoft Visual C++, Macintosh Cross-Development Addon, versions 4.0, 4.0b

SYMPTOMS

User-defined onexit, atexit, and cexit routines are not called for PowerMac applications using the C run-time dynamic-link library (DLL), /MD or /MDd.

CAUSE

DLLs and applications have different arrays of onexit pointers. The Win32 libraries have a method for ensuring both arrays are run through when the application terminates; however, this was not put in place for PowerMac DLLs.

Also, note that special handling is required for user-built DLLs!

RESOLUTION

Following are some possible ways to resolve this problem:

• Use the static version instead of the DLL version of the C run-time libraries.



• Clean up in the destructor of a global C++ object.

Additional query words: _cexit cexit _onexit
