UMENTRYABS

Use the UMENTRYABS macro to specify an absolute entry point.

The entry point in your source code does not, in general, match the absolute entry point in your binary. By default, the entry points and absolute entry points used by the Build utility depend on the type of product being built (specified by the UMTYPE macro) and on whether ASCII or Unicode is being used as the character set (specified by the USE_MFCUNICODE macro).

The following table lists the standard values of the entry points and the absolute entry points:

UMTYPE	Entry Point	Absolute Entry Point
windows (ASCII)	winmain	WinMainCRTStartup
windows (Unicode)	wwinmain	wWinMainCRTStartup
console (ASCII)	main	mainCRTStartup
console (Unicode)	wmain	wmainCRTStartup
nt		NtProcessStartup
ntss		NtProcessStartup
os2		NtProcessStartup
posix		__PosixProcessStartup

Use the UMENTRYABS macro to override the absolute entry point. For example, you might want the absolute entry point to be main rather than mainCRTStartup. In this case, you would use the following setting:

UMENTRYABS=main
