CTYPE Macros Function Incorrectly

ID: Q94323

The information in this article applies to:

Microsoft Win32 Software Development Kit (SDK), versions 3.1, 3.5, 3.51, 4.0

SUMMARY

When an application that is linked to CRTDLL.LIB is compiled without defining _MT and _DLL, the CTYPE.H family of macros will not operate correctly.

To define _MT and _DLL on the CL command line, just add the following to the command line:

-D_MT -D_DLL

By adding these defines, the CTYPE macros will be properly initialized.
